Description

The present invention relates to a measuring device designed to analyze a fluid tube; the present invention relates to a measuring and evaluation device which has such a measuring device and an electronic device for evaluating the measuring device data; and the present invention relates to a measuring data system which has at least one measuring and evaluation device and a second electronic device for evaluating and/or storing the information of the measuring and orientation data.

The measurement method underlying spectrometry is based on the known physical phenomenon that a beam of light experiences a weakening (extinction) when it passes through a fluid. The weakening is proportional to the concentration of the analyte and the measurement distance in the fluid that the beam of light must pass through. This physical relationship is described by the Lambert-Beersche extinction law. The spectrometer evaluates its measurements to determine the concentration of the analyte in the fluid and the result of the measurement is displayed on the screen.

WO 2010/146110 A1 reveals a non-slip, portable spectrometer for measuring at least one analyte in a fluid sample.

The present invention is intended to provide an improved measuring device which allows for a more compact design.

This task is solved by a measuring device according to claim 1, a measuring and evaluation device according to claim 14 and a measurement data system according to claim 16.

A measuring instrument designed to analyse a fluid sample or a luminescent sample shall be provided, the measuring instrument having a radiation receiver to receive a beam of light or radiation emitted by the fluid sample along a measuring path, and the measuring instrument having at least one connecting device to connect an external electronic device to transmit the measuring signals from the radiation receiver to an evaluator in the external electronic device to evaluate the measuring signals.

The idea underlying the present invention is to separate the measurement of a fluid sample or a luminescent sample from the evaluation of the measurement results of the fluid sample or the fluorescent sample, in order to make the measuring device more compact, which is particularly advantageous in the case of a portable measuring device. To this end, the evaluation of the measurement results of a fluid sample or a luminescent sample is not carried out in the measuring device itself but in an electronic device external to the measuring device. Only the measurement of the fluid sample or the luminescent sample is carried out by the measuring device.

The subclaims give advantageous modifications and refinements of the present invention.

The invention is explained in more detail below by means of examples of implementations, referring to the figures in the accompanying drawing.

In the figures, the same reference numbers refer to the same or similar functional components, unless otherwise stated.

Figure 1 shows an embodiment of a spectrometer 1 as a measuring device 100.

The spectrometer 1 is used to analyze a fluid sample 3 by measuring, for example, the concentration of at least one analyte in the fluid sample 3.

The fluid sample 3 may be a liquid, a gas or a liquid mist, and a liquid sample or a gaseous fluid tube, such as smoke, may also contain additional solid particles.

The spectrometer 1 is designed as a measuring device 100 to measure clear fluid samples. The spectrometer 1 as a measuring device 100 may also be optionally designed to measure cloudy fluid samples, provided that these fluid samples are sufficiently permeable to the spectrometer for measurement by light from a light source of a light source or lighting device 4 of the spectrometer 1. Cloudy fluid samples that can be measured by the spectrometer 1 are, for example, solid suspensions in fluids. These include, for example, cloudy thin water, porous water, deposition water, sewage, soil and soil manure samples. For example, fluids such as serum, suspensions of body fluids, etc. Can also be measured by means of the spectrometer 1.

The spectrometer 1 can be used, for example, to determine the concentration of dissolved water components. The water sample can be taken from an aquarium, garden pond or swimming pool, etc. There are no restrictions on the origin of the water.

Examples of water content substances which can be detected with the spectrometer 1 are oxygen, ozone, chlorine (free chlorine, total chlorine), nitrogen compounds (total nitrogen), potassium, iron, zinc, heavy metals, ammonium, cyanuric acid, cyanide, urea, carbonate (hardness of water), hydrogen peroxide, chloride, nitrite, nitrate or phosphate. In particular, a spectrometer can also determine the pH of a fluid sample, e.g. a water sample, by using e.g. a one-component indicator, a phenolometer, or a two-component mixed indicator, e.g. a bromethol/thymol-black indicator, which is then automatically detected by the photometric indicator used.

The spectrometer 1 shown in Figure 1 according to an embodiment of the invention has a housing 31 with a light source or lighting device 4 to produce at least one beam of light 5. This light source or lighting device 5 is guided by a fluid sample 3 taken in the spectrometer 1. The light source or lighting device 4 may have at least one LED 32 or, as shown in Figure 1, an LED array 33 of several LEDs 32 as a light source, as shown in Figure 5 below. LEDS 32 may be used, for example, as laser LEDs. However, the invention cannot be limited to LEDs 32 and laser source LEDs in particular. Any other light sample designed to be measured by means of a fluid spectrometer is suitable for measuring 100 m of fluid as a measuring device 1.

As shown in the example shown in Figure 1, optionally, at least one or more optical devices 22 may be provided to collect and/or guide the light produced by the LED array 33 into an optical beam 21 of the spectrometer 1; such optical devices 22 are, for example, lenses, mirrors or prisms, etc.

The spectrometer 1 shall also have a sampling device 2 with a sampling device 9 for a fluid sample 3. The sampling device 2 shall also have a light receiver or radiation receiver to receive the light beam 5 generated in the light source or lighting device 4 of the spectrometer 1 and the fluid sample 3 taken in the sampling device 9 shall pass along a strip 7. For example, a photosensor 6 containing at least one photodiode shall be used as a light receiver or measuring device. Instead of a photosensor 6 any other light receiver suitable for receiving the light source or lighting device 4 of the spectrometer 1 may be used.

The photosensor 6 as a radiation receiver receives and converts the incident light beam 5 into electrical signals which can be evaluated for analysis or examination of the fluid sample 3. The electrical signals depend, for example, on the incident light power and/or wavelength of the light beam 5.

The embodiment of the spectrometer 1 of the invention shown in Fig. 1 as measuring device 100 has an optional analogue/digital converter 20 to convert an analogue signal from the light receiver or photosensor 6 in Fig. 1 into a digital signal or, conversely, to transmit it to an external electronic device 37 such as a PC, smartphone, tablet PC, server, etc. which evaluates the signals from the light receiver or photosensor 6 for this purpose. The electronic device 37 has, for example, an appropriate measuring device 109. The result of the evaluation can be determined by means of an appropriate electronic display, e.g. a display of the smartphone or tablet computer, and the display of the screen, e.g. a display of an external device 110 or a display of the screen, which can be used as the measuring device.

The external electronic device 37 together with the measuring device 100 constitute a measuring and evaluation device 115. This applies to all examples described with reference to Figure 1 and Figures 2 to 9 below.

In addition, the external electronic device 37 such as a smartphone, server, PC or tablet PC, etc., may have, in addition to or as an alternative to the evaluation device 109 and/or the display device 110, a GPS device 101, a timing device 102, a camera device 103, a storage device 104, a transmitting device 105, a receiving device 106, a scanner device 107 and/or a microphone device 108 which may be used or may be used in conjunction with the measuring device 100.

The data from the GPS device 101 can be used, for example, to determine the position of a measurement made by the measuring device 100. This allows the exact geographical position to be assigned to a measurement. In this way, it can be very easily verified, for example, whether a measurement was made at the correct place.

The time and/or duration of a measurement made by the measuring device 100 etc. can be determined by the measuring device 102 and can be used to verify, for example, that the measuring time has been observed and that the measurement has been correctly performed by a user of the measuring device 100.

The camera 103 also allows the user to record, for example, the location of the measurement made by the measuring device 100, to photograph the batch number of the sample or the detection reagent, etc., to name a few examples.

Similarly, the scanner 107 can be used, for example, on a smartphone or tablet PC to scan a code, e.g. a barcode, a 2D code, etc., e.g. a 2D code of a detector reagent used for measurement by the measuring device 100, etc. This can be used to check, for example, whether the expiry date of the detector reagent has been met, which detector reagent has been used, etc.

For example, the microphone device 108 may instruct a user of the measuring device 100 on how to operate the measuring device 100 and/or the user may dictate additional comments or information or a recording of the measurement to the external measuring device 100 by means of the microphone device 108.

The data of the GPS device 101, the timepiece 102, the camera device 103, the scanner device 107 and/or the microphone device 108 may be assigned or associated with the measurement data received from the measuring device 100; at least some or all of the data or signals may be stored in the storage device 104 of the external device 37, e.g. a smartphone or tablet PC, etc.; evaluated in the evaluation device 109 of the external electronic device 37, on the display device 110, e.g. a screen or display display displaying the external electronic device 37; and/or transmitted to another external device 137, with a dotted line in Figure 1. This may be transmitted to any device, e.g. a server, via a satellite device 105 or a satellite device 37; and in particular, the data may be transmitted by wireless transmission via the electronic device 105 or by wireless transmission via the satellite device 105 or by means of a wireless signal, as shown in Figure 37 and 105 in particular, the data transmitted to the device 105 or its wireless devices 105 and 105 may be transmitted via a wireless signal.

Furthermore, the external electronic device 37 e.g. the smartphone or tablet PC can receive, via the other external device 137, e.g. a server, data or signals, in particular commands, etc. For example, the external electronic device 37 can control and/or control the measuring device 100 via the other external device 137. The external electronic device 37 directs the receiving device 105 to receive data or signals, e.g. commands, etc. wirelessly and/or wired, the measuring device 100 and the other external electronic device 137. This applies to all examples as shown in Figures 1-9.

Optionally, the spectrometer 1 as measuring device 100 may itself have at least a separate storage device 111 for storing or interstitial storage, for example, of measuring data or measuring signals, etc. The storage device 111 may be accessed by the external electronic device 37.

The spectrometer 1 with its sampling device 2 and the photosensor 6 forms a measuring line 7 in beam channel 21 of the beam 5. In sample 9 of the sampling device 2, the fluid sample 3 is introduced into the measuring line 7. The measuring line 7 can be used, for example, to determine the volume of the fluid sample 3 introduced. The measuring line 7 specifies a corresponding layer thickness of the fluid sample 3 which the light beam 5 must pass through in order to reach the light source or lighting device 4 from the light receiver or photosensor 6.

The microcontroller 34 controls and/or regulates the light source or lighting device 4. In this way, the microcontroller 34 controls and/or regulates, for example, the light intensity, the light wavelength and/or the luminous duration of the light source or lighting device 4. The microcontroller 34 can also be connected to the described electronic device 37 for transmitting the signals of the photodiode or photodiode 6 111 directly to the electronic device 37 so that the electronic signal 37 is transmitted from the photodiode or photodiode in the direction of the photodiode or photodiode.

For example, the microcontroller 34 may be configured in an embodiment of the spectrometer 1 of the invention to control the LEDs 32 of the LED array 33 together or instead individually or independently of each other. For example, the microcontroller 34 may control the light source or lighting device 4 depending on the light intensity received by the light receiver 6. For example, if too little light is received by the light source or lighting device 4 from the light receiver 6, the light intensity and/or light duration can be appropriately increased by the microcontroller 34. However, this is not limited to this example. This may be done in addition to the light or light intensity or light intensity and may also be controlled by means of a lighting controller 34 and/or a lighting controller depending on the embodiment.

In addition, the microcontroller 34 may be additionally or alternatively trained by means of the external electronic device 37 connected to the spectrometer 1 to control and/or regulate the light source or lighting device 4 as indicated by a dashed line in Figure 1. The measuring device 100 and/or the external electronic device 37 may have a control device, such as the microcontroller 34, to control and/or regulate the measuring device 100. Software for the control and/or regulating of the measuring device 100 may also be stored in its own storage device 111 and/or stored by the external electronic device 37 for the control and/or regulating of the measuring device 100.

The sampling device 2 included in housing 31 of the spectrometer 1 is mounted in the example shown in Figure 1 in the housing 31 and is designed to be mounted and unmounted in the housing 31 and the sampling device 2 may optionally be additionally trained in several pre-defined exit or entry positions, the sampling device 2 being trained in a single or stepwise mode.

Furthermore, the retractable and retractable sampling device 2 is optional included in the housing 31 for example, light-tight, gas-tight and/or liquid-tight, so that, for example, light, gas and/or liquid cannot unintentionally enter the housing 31 between the sampling device 2 and the housing 31.

In an alternative embodiment of the spectrometer 1 of the invention, the sampling device 2 is either fixed to the housing 31 or partially formed with the housing 31.

In the sampling device 2, the sampling device 9 shall be so designed that a fluid sample 3 to be examined by the spectrometer 1 can be introduced into the sampling device 9, the fluid sample 3 being introduced in the measuring range 7 between the photosensor 6 and the light source or lighting device 4 or a light conductor 8 of the sampling device 2.

In the embodiment of the spectrometer 1 as measuring device 100 shown in Figure 1, the light conductor 8 is additionally optional in the sampling device 2 in the beam channel 21 of the beam 5 in the longitudinal direction of the sampling device 2 in addition to the light conductor 8 in the sampling device 2.

In the example shown in Figure 1, the light guide 8 is fixed at one end 14 in the housing 31 of the spectrometer 1 and is incorporated with the other end 15 in the sampling device 2 which is movable along the light guide 8. The light guide 8 may optionally be sealed in addition to the sampling device 2, in particular liquid-tight 2 and/or gas-tight. This prevents the liquid from entering the housing 31 unintentionally when the sampling device 2 is immersed in an analytical fluid.

Optionally, at least one optical device 22 such as a lens 35 shall be placed between the photosensor 6 and the sampling device 9 in the sampling device 2 and the lens 35 may be provided, for example, to bundle or collect the light which is passed from the light source device 4 through the fluid sample 3 taken into the sampling device 2.

Outside the invention, the sample sample 9 of the sampling device 2 may be designed to introduce a fluid sample into sample 9 by immersion of the sample sample device 2 in the fluid sample, e.g. a liquid and/or a gas. Additionally or alternatively, the sample sample 9 may be designed to take a sample container, e.g. a bucket, with which to collect the fluid sample, as shown in Figures 2, 3 and 4 below. Figure 2 shows an example of implementation according to the invention, the examples in Figures 3 and 4 do not correspond to the invention.

As described above, the light source or lighting unit 4 with its LED array 33 as light source generates a beam of light 5 which is received by the photosensor 6 of the sampling unit 2. The photosensor 6 is incorporated into a sensor recording 13 of the sampling unit 2 and converts the incident light beam 5 into electrical signals and, in the embodiment example in Fig. 1, passes these to the analogue/digital converter 20 which converts the electrical signals of the photosensor 6 into digital signals, for example, and passes them on to the microcontroller 34. The microconchometer 34 transmits the signals to a range of spectrum 111 in an external direction 37 and transmits the resulting signals to an external direction 37 or to an external direction 37 for the analysis of the sample. The resulting signals can be stored in an electronic data storage or in an analogue data analyzer, or alternatively, in a data centre.

The analogue/digital converter 20 is connected to the photosensor 6 e.g. wired, etc., to receive the signals of the photosensor 6. The invention is not limited to a wired connection of the photosensor 6 and the converter 20. Any other type of connection suitable for the converter 20 to receive the signals of the photosensor 6 may be provided.

The spectrometer 1 shall have at least one connecting device 36 to connect the external electronic device 37 such as a PC, tablet PC, server and/or smartphone, etc. to the spectrometer 1.

The spectrometer 1 transmits the data from the light receiver, e.g. photosensor 6, to the electronic device 37 for evaluation and the result is displayed, for example, on a display or screen of the electronic device 37.

The electronic device 37 performs the evaluation of the light-receiver signals by means of suitable software. The results of the evaluation can then be displayed on a display or screen of the electronic device. Furthermore, the electronic device 37 can optionally control the microcontroller 34 of the spectrometer 1 via suitable software and, for example, control and/or regulate the light sources or lighting device 4 by means of the microcontroller 34. This allows a compact design of the spectrometer 1 as the evaluation and display of the results of the evaluation is not done by the spectrometer 1 itself but by an external electronic device connected to the spectrometer 1. Similarly, the external electronic device 37 or another measuring device 34 can be fitted to the microcontroller and/or control device 100.

A user of the spectrometer 1 as measuring instrument 100 may select a measuring programme from the external electronic device 37 and the external electronic device 37 may then control the user's own microcontroller or the microcontroller 34 of the measuring instrument 100 to perform the measurement selected by the user, for example the measurement of the pH or nitrate content of a sample, etc.

Such measuring programmes and other software programmes for controlling and/or controlling the measuring instrument 100 may be provided as software, e.g. application software, to be loaded onto the external electronic device 37, e.g. a smartphone, tablet PC, PC or server, etc.

Additionally or alternatively, software programs, e.g. measurement programs, etc., may be stored via the external electronic device 37 also on the memory device 111 of the spectrometer 1 for the microcontroller 34 of the spectrometer 1 for retrieval.

The connection device 36 of the spectrometer 1 may be used to connect at least one external electronic device 37 and transmit data or signals from the photosensor 6 to the electronic device 37. The connection device 36 of the spectrometer 1 may, for example, have a cable connection and/or a wireless connection. The cable connection may be designed, for example, to connect a USB cable of a PC, tablet PC, smartphone, laptop, server, etc., but the invention is not limited to such a connection. A wireless connection may be provided, for example, a Bluetooth connection, a radio connection, etc., but the invention is not limited to the examples of wireless connections mentioned above.

The electronic device 37 has, as described above, an appropriate evaluation software for evaluating data or signals from the spectrometer 1 and in particular signals from the light receiver, e.g. photosensors. The evaluation software can be loaded, for example, as an application software to the external electronic device 37 and used as a measuring device 100 in the evaluation device 109 to evaluate the data or signals from the spectrometer 1. The result of the evaluation of the fluid sample 3 by evaluating the signals from the light receiver or photosensors 6 in Fig. 1 can, as described above, be displayed on a display as an indicator device 110 of the electronic device 37 and optionally provide additional graphic samples. The external instrument 37 can also be displayed on an electronic controller 34/ 1 and microcontroller 34/ 1 to control the spectrometer and microcontrollers.

The evaluation software and control software may be provided, for example, as an evaluation AP or app (evaluation application or evaluation application software) and a control AP or app (evaluation application or control application software) for the spectrometer 1, which can be downloaded by a user via his electronic device 37 such as a PC, tablet PC, server or smartphone via the Internet. The user may then connect his electronic device 37 to the spectrometer 1, select a measurement, e.g. pH meter or nitrate content sample, and have a fluid 3 measured by means of the 37 m spectrometer input and output by means of his electronic device 37 in the direction of the measurement device. This is convenient since an electronic display can be installed in the direction of the 37 m spectrometer output and the result can be measured in the direction of the 37 m spectrometer output.

The spectrometer 1 may be a grid-independent spectrometer 1 as shown in Figure 1 which has its own power source 11, e.g. a battery and/or battery. Such a spectrometer 1 may therefore be used as a portable spectrometer 1 as it does not require a power connection 11 due to its own power source and can therefore be carried anywhere to make measurements on site. Similarly, the spectrometer 1 may also be a grid-independent spectrometer which can be connected to a power source. For this purpose, the spectrometer 1 may be connected to an electrical power supply of the electronic device 37 or another external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an external power supply 37 or to an electrical power supply 37 or to an electrical power supply 37 or to an electrical power supply 37 or to an electrical power supply 37 or to an electrical or to an electrical power supply 37 or to an electrical or to an electrical power supply 37 or to an electrical or to an electrical or to an electrical power supply.

As shown in the example shown in Figure 1, the spectrometer 1 has an optional switch 38 to turn the spectrometer 1 on and off. This switch 38 is used to turn on and off, for example, the light source or lighting device 4, the photosensor 6 and the microcontroller 34, thus saving energy.

The measuring range 7 of the spectrometer 1 can be set or set as described above, and the sampling device 2 is fixed to the housing 31.

The measuring range 7 of the spectrometer 1 can also be provided as a variable or variable range, for which the sampling device is located in the housing 31 of the spectrometer 1 and is retractable.

This allows analyte to be determined at very low or very high concentrations in the fluid sample 3. For example, the measuring range 7 is selected to be relatively large if it is an analyte present at only very low concentrations in the fluid sample 3. This allows a suitable volume or layer thickness of the fluid sample 3 to be provided in the spectrometer 1 and measured by it.

In the embodiment of the spectrometer 1 of the invention shown in Figure 1, the measuring range 7 is modified by inserting and exiting the sampling device 2 into the housing 31. If the sampling device 2 is inserted into the housing 31, as indicated by a dotted line, the measuring range 7 is shortened, resulting in a lower volume or layer thickness of a sample of fluid 3 to be measured being absorbed in the measuring range 7 of the sampling device 2.

On the other hand, if the sampling device 2 is removed from the housing 31, the measuring band 7 and the band 7 are enlarged according to the cross-section of the sampling device 9 and a larger volume or layer thickness of a sample of fluid 3 to be measured may be taken in band 7 of the sampling device 2, whereby in an embodiment of the spectrometer 1 of the invention, the light conductor 8 incorporated in the beam-beam of the sampling device 2 may be preferably additionally sealed against the sampling device 2, in particular to prevent penetration of a sample of fluid 3 into the band 31 of the spectrometer 1.

Similarly, in another embodiment of the invention, sample vessels of different size may be provided for inclusion in sample sample 9 of the sampling device 2. For example, if the measuring range 7 and the corresponding cross-section of sample 9 are reduced, as indicated in Fig. 1 by a dotted line, a sample vessel with a correspondingly reduced cross-section of sample 9 and a fluid sample 3 included in it may be inserted into it. In this case, additional sealing of the light conductor 8 against the sample device 2 may be dispensed with.

An alternative not shown embodiment of the spectrometer 1 of the invention as a measuring device does not provide for an additional light conductor 8 in the sampling device 2. Instead, the measuring range 7 is provided directly between the photosensor 6 and the light source or lighting device 4. The measuring range 7 is also modified by the fact that the sampling device 2 is retractable and retractable in the housing 31 of the spectrometer 1. Similarly, sample containers with different cross-sectional sizes can be installed and used in the correspondingly enlarged or reduced sampling range of the sampling device 2, as described above.

In Fig. 2 a sample sample 9 from a sampling device 2 is shown as a measuring device 100 in an embodiment of a spectrometer 1 of the invention. In Fig. 9 a sample container 24 with a fluid sample 3 for analysis by the spectrometer 1 is shown. The sample 9 is shown in a cross-sectional view in the longitudinal direction of the sampling device 2. Furthermore, the longitudinal axis 39 of the sampling device 2 is shown. The arrangement of the light receiver is not shown in Fig. 2 and the following Fig. 3 and 4 for reasons of clarity.

As shown in Figure 2, sample sample 9 is open on both sides of the sampling device 2 to allow passage of, for example, a sample tank 24 transversely through the sampling device 2. To this end, sample sample 9 of sample device 2 has an opening 25, 26 on each of the two opposite sides, for example, the openings 25, 26 being rejuvenated in their cross-section so that a sample tank 24 with a corresponding rejuvenated cross-section can be inserted and held in sample sample 9 as shown in the example in Figure 2. Optionally, the openings 25, 26 can be equipped with additional non-reflective sealing devices, sealing the sample, and, in particular, the sample 9 and 9 is designed to be sealed by a gas and liquid sealing device, as shown in Figure 24.

Furthermore, Fig. 3 shows a sample sample 9 sample device 2 as sample device 100 in accordance with an example of a non-invented spectrometer 1.

As shown in Figure 3, sample sample 9 of the sampling device 2 has an opening 25, 26 on each of the two opposite sides, with the same cross-section of the openings 25, 26, so that a sample vessel 24 with a corresponding cross-section can be introduced into sample 9.

For example, to hold a sample tank 24 in record 9, record 9 and/or the sample tank 24 may be provided with an elastic section 27 or an elastic ring, e.g. made of rubber and/or foam, to hold the sample tank 24 in record 9 after it has been introduced into record 9.

Optionally, the elastic section 27 may also be further trained as a sealing device 23 to increase the density of the sample tank 24 relative to sample tank 9, and in particular gas-tight, liquid-tight and/or light-tight seals of the sample tank 24 relative to sample tank 9, so that no gas, liquid and/or light can pass through the elastic section 27 into the sample collection device 2 between the sample tank 24 and sample tank 9.

In addition or alternatively, the sample vessel 24 may be fitted with a cuff 28, e.g. an elastic or rigid cuff, and/or a flange (not shown) to allow the sample vessel 24 to rest on the top of sample collection 9, which may also prevent the unintended sliding of the sample vessel 24 from sample collection 9, and an additional sealing device may be provided between sample collection 9 and sample collection tank 24 if necessary.

In Fig. 4 an excerpt of a sample sample 9 of a sampling device 2 is shown as a measuring device 100 in accordance with another example of a non-invented spectrometer 1.

As shown in Figure 4, sample no. 9 forms a depression 29 to take a sample tank 24 with a fluid sample 3. The length of the depression 29 can be determined by the sample no. 2 or the sample no. 2 can be further deepened in the area of sample no. 9 to take a sample no. 24 as indicated by a dashed line in Figure 4. In addition, the depression 9 and/or the sample no. 24 can be closed with a lid no. 30, in particular gas, liquid and/or light-tight.

The sampling device of the spectrometer 1 described above with reference to Figures 1 to 4 as measuring device 100 may be optionally made of an additional material, e.g. acid-resistant, if the fluid sample to be measured is acidic or acidic.

The external electronic device 37 described above with reference to Figure 1 is an external evaluation and display device for evaluating the information or signals from the light receiver 6 of the spectrometer and for displaying the result or results of the evaluation of the spectrometer measurements.

The spectrometer 1 itself is merely a measuring device with the equipment necessary for the measurement of the fluid sample, such as the light source or lighting device 4, the light receiver 6, the sampling device 2, the microcontroller 34 and the transducer 20.

By separating the evaluation of the spectrometer measurements and the display of a respective evaluation result from the spectrometer and by restricting the spectrometer to the measurement and the necessary devices, such as the light source device and the light receiver, the spectrometer can be constructed as a small and compact measuring device 100.

In Fig. 5 an example of spectrometer 1 as measuring device 100 is shown as described in Fig. 1-4 above. The spectrometer 1 in Fig. 5 has a retractable measuring range 7. The statements made previously with regard to the spectrometer in Fig. 1-4 are also valid for the spectrometer shown in Fig. 5.

The spectrometer 1 as measuring device 100 in Fig. 5 has several light sources as light source or lighting device. The light sources are preferably LEDs 32, and laser LEDs. The light sources are designed to emit almost monochromatic light with a wavelength preferably 250-750 nm. The light sources are preferably designed to emit light of different wavelengths or different wavelengths. For example, one light source can be designed to emit light with a wavelength between 610 and 750 nm and the other light source can be designed to emit a light source with a wavelength between 590 and 610 nm.

The light source (s) may be arranged in a semi-circular pattern and preferably form an array 33.

The spectrometer 1 as measuring device 100 also has a photosensor 6 for receiving the light beam 5. The photosensor 6 converts the incident light beam 5 into electrical signals or data. The electrical signals or data depend on the incident light power and/or wavelength of the light beam 5. The photosensor 6 is preferably a photodiode.

The spectrometer 1 is also equipped with a measuring range 7 in the beam 5 beam beam path. The fluid sample 3 can be introduced into the measuring range 7 and the measuring range 7 is designed to be variable. Other In the beam path of beam 5 a light guide 8 is arranged, for example in the form of an acrylic rod, macrolone rod, glass rod or fiberglass cable.

The headlamp 8 has a first section 14 which is fixed in a handhold designated as housing 31.

The inner diameter of the ring-shaped cross-section of the housing 112 corresponds essentially to the outer diameter of the circular cross-section of the light conductor 8.

The case 112 is provided with several longitudinal holes 113 according to an example not in conformity with the invention. Two longitudinal holes 113 may be facing each other, as shown in Figure 5. Furthermore, for example, two such pairs of opposite longitudinal holes 113 may be provided along the beam path of the beam 5 at a distance from each other along the case 112. Regardless of the position of the case 112 in relation to the case 31 or the light guide 8 respectively, one of the longitudinal holes 113 is always connected to the measuring line 7 i.e. the fluid sample 3 can be taken from the fluid, for example a vessel. One such sample can be taken simply by the insertion of the longitudinal holes 113, so that the fluid sample 1124, as shown in the example, can also be taken from the end of the case 114.

The case 112 has a first section 41 which extends into the case 31. Section 41 is mobilityally incorporated into a reception area 42 of the case 31 along the radius of the light beam 5 in the case 31. For example, section 41 may be provided with an external wind which interposes into a corresponding internal wind in the case 31. Alternatively, section 41 may be provided externally with grilles which interpose with corresponding counter-grilles in the case 31 and thus allow a gradual displacement of the case 112 in relation to the case 31.

A second section 43 of the case 112 extends outwards from the housing 31 and encloses the second section 15 of the light guide 8. To the second section 43 of the case 112 is connected a third section 44 of the case 112 which limits the volume of the fluid sample 3. To the third section 44 is connected again the end piece 114. The end piece 114 seals the circular cross-section of the case 112 fluid-tightly.

The measuring distance 7 is thus defined between the front end 45b of the end piece and a front side 45a of the light guide 8.

Endpoint 114 shows the photosensor 6 and optionally an additional lens 22 as an example of an optical device which, for example, concentrates the incident light beam 5 on the photosensor 6. Other examples of optical devices in addition to a lens are, for example, mirrors and prisms. Such optical device 22 can be used in all embodiments of the invention as illustrated in Figures 1-9 and is used to concentrate, collect, guide and/or scatter light, for example, the light source or lighting device and a luminescent sample described below.

Now, by moving the casing 112 into or out of the reception area or reception area 42 of housing 31 the measuring range 7 is adjusted and can be easily adapted to the requirements for a concentration measurement of a particular analyte.

On the other side of the front of the light-guide 8 the beam 5 is coupled, and means 47 may be provided to connect one or the other light source, in this case LED 32, to the light-guide 8 by means of a light conductor.

In addition, the spectrometer 1 may optionally have an additional microcontroller 34 and/or be coupled to such a microcontroller of an external device 37; likewise, the spectrometer 1 may optionally have at least its own storage device 111 as described above, a power source 11 as well as an analogue/digital converter 20 and/or a switch device 38 to turn on and off the spectrometer 1 as measuring device 100.

The spectrometer 1 as measuring device 100 shall, as described above with reference to the spectrometer described in Figures 1 to 4, have at least one connecting device 36 for connecting an external electronic device 37 such as a PC, tablet PC, server and/or smartphone, etc. The connecting device 36 shall be a wired connection, e.g. a USB cable connection, etc., and/or a wireless connection, e.g. a Bluetooth connection or a radio connection, etc.

The data or signals from the photosensor 6 as a light receiver are transmitted to the electronic device 37 for evaluation by an evaluation device 109 by means of the spectrometer 1 as a measuring device 100, as described above. The result of the measurement is displayed, for example, on an indicator device 110 such as a display or screen of the electronic device 37. The electronic device 37 performs the evaluation of the light receiver signals by means of appropriate software.

In addition, the electronic device 37 may optionally control the microcontroller 34 of the spectrometer 1 by means of appropriate software and, by means of the microcontroller 34, control and/or regulate, for example, the light source or lighting device 4 and/or the photosensor 6.

The external electronic device 37, such as a smartphone, PC, server or tablet PC, etc., shall have, as described above with reference to Figures 1 to 4, a GPS device 101, a timing device 102, a camera device 103, a storage device 104, a transmitting device 105, a receiving device 106, a scanner device 107 and/or a microphone device 108 which may be used together with the measuring device 100 as described above.

Figures 6 and 7 show another example of a measuring device 100 not in conformity with the invention. Figures 6 and 7 show the measuring device 100 in a close-up view, with part of the housing 49 removed in Figure 6. The measuring device 100 shown in Figures 6 and 7 is designed to measure or analyze luminescent samples.

Luminescence is the optical radiation of a physical system that occurs when it passes from an excited state to a ground state.

Depending on the type of stimulation, different types of luminescence are distinguished, including, for example, photoluminescence, chemoluminescence and bioluminescence.

In photoluminescence, a system is excited by photons. Depending on the time period between excitation and emission of light, a distinction is made between phosphorescence and fluorescence.

Chemoluminescence is a chemical reaction that stimulates the system, for example by using luminol to detect blood.

In bioluminescence, the system is stimulated by a chemical reaction in a living organism, such as a cell, a bacterium or an animal, such as a light beetle, in which luciferin is oxidized.

For the analysis of a luminescent sample, the measuring device 100 shall have a sampling chamber 50 in housing 49 in which a sample container 51 can be inserted and analyzed with the luminescent sample 52, which may be locked, for example, by means of a lid, in particular a closure, so that the sample cannot escape unintentionally from the sample container 51.

The sample container 51 shall be transparent, for example, made of transparent plastic or glass, to block the radiation emitted by the luminescent sample 52, e.g. visible light, and, if necessary, to block radiation from at least one additional lighting device 55 to illuminate the luminescent sample 52, to stimulate its illumination.

The sample container 51 may be integrated into the housing 31 either solidly or solubly. If the sample container 51 is solubly integrated into the housing 49, it may be easily removed from the housing 49 by means of a corresponding housing opening 54, filled with the luminescent sample 52 and then inserted into the housing 49. If the sample container 51 is solidly integrated into the housing 49, the cover for filling the sample container 51 may be removed and, after filling the sample container 51, re-closed. The cover may also be transparent as in the case of the sample container 51 or opaque, depending on, for example, the use of additional lighting and where it is installed.

The housing opening 54 for inserting and/or filling the sample container 51 shall preferably be closed with a covering, e.g. a closing cap 53, in particular a light-tight closing, to ensure that no light from outside can penetrate the housing 49 and its sample chamber 50 and distort the measurement result.

In addition, housing 49 preferably in sample chamber 50 of housing 49 shall include at least one radiation receiver 56 for receiving radiation emitted by the luminescent sample 52 and converting it into electrical signals. For example, a light sensor or photosensor may be used as a radiation receiver 56 for receiving radiation such as light, etc., the luminescent sample 52 may include a light sensor or photosensor. The photosensor may have at least one photodiode. Any other suitable radiation receiver or combination of radiation receivers designed to receive radiation emitted by the luminescent sample, e.g., a light sensor, etc., may be used instead of a light sensor or photosensor.

Optionally, in addition, a photoluminescent sample 52 may be used as an example of a luminescent sample 52 for analysis, in which case the housing 49 may contain at least one additional lighting device 55; the luminescent sample 52 shall be illuminated by means of the lighting device 55 with an appropriate radiation to stimulate the luminescent sample 52 to illuminate; such luminescent or photoluminescent samples 52 are, for example, fluorescent samples or phosphorescent samples; the lighting device 55 may also be located, for example, in the sample chamber 50 as indicated by a vertical line in Figure 6. For example, the lighting device 55 may also be integrated into the measuring cover of the sample 51 or be located at any other suitable location for measuring the sample 50.

For example, several lighting devices 55 may be provided, whereby the lighting devices 55 emit all light of the same wavelength or light of different wavelengths to illuminate the luminescent sample 52. This may allow a luminescent sample 52 to be examined to be illuminated, for example, alternately, with light of different wavelengths, for the determination of, for example, several or different analyte.

The measuring device 100 is capable of being connected to an external electronic device 37 by at least one connecting device 36 with a cable connection and/or a wireless connection. The cable connection may, as described above with reference to Figures 1-5, be designed, for example, to connect a USB cable of a PC, tablet PC, smartphone, laptop, server, USB stick, etc., but the invention is not limited to such a connection. For example, a Bluetooth connection, a wireless connection, etc., may be provided as a wireless connection, but the invention is not limited to the examples of wireless connectors mentioned above.

The external electronic device 37 such as a smartphone, server or tablet PC, etc., may, as described above with reference to Figures 1 to 5, have a GPS device 101, a timing device 102, a camera device 103, a storage device 104, a transmitting device 105, a receiving device 106, a scanner device 107 and/or a microphone device 108 which may be used with the measuring device 100 or not.

Optionally, the measuring device 100 may also have at least a separate storage device 111 for storing or interim storage, for example, of measuring data or measuring signals, etc. The storage device 111 may be accessed by the external electronic device 37.

In addition, the radiation receiver 56 of the measuring instrument 100 may be connected to an evaluation device 109 of the external electronic device 37 and the signals or data of the radiation receiver 56 transmitted wirelessly or wired to the evaluation device 109, for example, the signals or data of the radiation receiver 56 for the analysis of the luminescent sample 52 are evaluated in the evaluation device 109 of the external electronic device 37 and the results of the evaluation can be displayed on an evaluation device 110, e.g. a display or screen, of the external electronic device 37; in this way, the data or signals of the measuring instrument 100 may also be stored in the storage facilities of the external electronic device 104 37

Furthermore, the spectrometer 1, as described above, may optionally have an additional microcontroller 34 and/or be pairable with such a microcontroller of an external device 37; the microcontroller 34 may be used, for example, to control and/or regulate the illumination of the respective lighting device 55 and/or to control and/or regulate the sensitivity of the radiation receiving device 56, etc. For example, the microcontroller 34 may control and/or regulate the illumination duration, the illumination intensity, the illumination interval of the lighting device 55, etc. However, the installation is not limited to the examples mentioned above.

The measuring instrument 100 described above may also optionally have at least its own storage device 111, a power source 11, an analogue/digital converter 20 and/or a switch device 38 to turn the measuring instrument 100 on and off.

The sampling chamber 50 may also be additionally light-tight or shielded from ambient light in the housing 49 of the measuring instrument 100 so that, in addition to the light of any additional lighting device 55 to illuminate the luminescent sample 52 in the sampling chamber 50, no light from outside the housing 49 of the measuring instrument 100 or, if any, from light sources within the housing 49 may be unintentionally introduced into the sampling chamber 50 and the sample 52 contained therein.

In Figure 7 the measuring device 100 is shown as shown in Figure 6 and its housing 49. As described above with reference to Figure 6, the housing opening 54 for inserting and/or filling the sample tank 51 is preferably closed tightly, in particular at least light-proof, by a covering element, e.g. a closing cap 53 in Figure 7. When the housing opening is closed tightly, no unwanted light from outside enters the housing 49. As described above with reference to Figure 6, the sample chamber inside the housing 49 may also be additionally light-proofed or protected by a surrounding screen. In this way, for example, a sample is only illuminated by an additional lighting device 55 but not unwanted by the interior lighting device 55 if necessary.

As shown in Figure 7, the measuring instrument 100 may be designed as a portable measuring instrument 100 and may have its own power source 11 as indicated by a dashed line in Figure 7 to power devices such as a lighting device 55 and/or a radiation receiver device 56. The power source 11 may be, for example, a battery device and/or a battery. An external power source may be connected to supply the measuring instrument 100 with power, for example, by means of the connecting device 36, e.g. a cable connection.

In an embodiment of the measuring device not in accordance with the invention shown in Figures 6 and 7, the cover element 53 may be designed to close the housing opening at the same time as the sample container 51 so that the separate cover for the sample container is removed.

The apparatus 100 described above in the example given in Figures 6 and 7 can be used as a luminescent sample to analyse solid, liquid, paste, powder and/or gaseous samples and organisms, cells, animals such as insects, etc., provided they are luminescent.

Figure 8 shows a non-inventive example of a measuring device 100 designed to measure or analyse luminescent samples, as shown in Figures 6 and 7, where the measuring device 100 shown in Figure 8 has essentially the same structure as the measuring device shown in Figures 6 and 7, so that reference is made to the description in Figures 6 and 7 to avoid unnecessary repetition.

The measuring device 100 shall have a housing 49 with a sample chamber 50 for the analysis of a luminescent sample, into which a sample container 51 can be inserted and analyzed with the luminescent sample, the sample container 51 being, for example, lockable by means of a lid 57 and, in particular, tightly lockable so that the sample cannot escape unintentionally from the sample container 51.

The sample container 51 shall be transparent to prevent the radiation emitted by the luminescent sample from passing through and, if necessary, to prevent radiation from passing through at least one additional lighting device to illuminate the luminescent sample to induce re-illumination.

The sample container 51 may be firmly or solubly integrated into the housing 49. If the sample container 51, e.g. a glass vial, is soluble in the housing 49, it may be easily removed from the housing 49 by a corresponding housing opening 54 of the housing 49, filled with the luminescent sample and then reinserted into the housing 49. If the sample container 51 is firmly integrated into the housing 49, the lid 57 for filling the sample container 51 may be removed and, after filling the sample container 51, re-closed. The lid may also be transparent, opaque or opaque, as in the case of the sample container 51.

The housing opening 54 of housing 49 for inserting and/or filling the sample container 51 shall be designed to be locked, in particular to be light-tight, by means of a cover element, e.g. a closing valve 58 or a closing cap not shown, the closing valve 58 being fixed to the housing 49 of the measuring device 100 in a rotatable manner as shown in the example shown in Figure 8.

This ensures that no light from outside can penetrate the housing 49 and its sampling chamber 50 and distort the measurement result.

In addition, in the sampling chamber 50 of the measuring head, for example, at least one radiation receiver is provided to receive the radiation emitted by the luminescent sample and convert it into electrical signals. As a radiation receiver for receiving radiation, such as light, etc., the luminescent sample may be used, for example, a light sensor, photomultiplier, avalanche diode or photosensor. The photosensor may have at least one photodiode. Instead of a light sensor, photomultiplier, avalanche diode or photosensor, any other suitable radiation receiver or combination of radiation receivers designed to receive light emitted by a luminescent sample, e.g. a photomultiplier, avalanche diode or photosemulator, may be provided.

Optionally, in addition, an example of a luminescent sample may be provided for the analysis of a photoluminescent sample, in which case 49 at least one additional lighting device shall be provided. The luminescent sample shall be illuminated by means of the lighting device with an appropriate radiation to stimulate the luminescent sample to illuminate. Such luminescent or photoluminescent samples are, for example, fluorescent or phosphorescent samples. The lighting device is also arranged approximately in the sample area, e.g. 50.

For example, several lighting devices may be provided, all of which emit the same light or light of different wavelengths to illuminate the luminescent sample.

The measuring device 100 is capable of being connected to an external electronic device 37 by at least one connecting device 36 with a cable connection and/or a wireless connection. The cable connection may, as described above with reference to Figures 1-7, be designed, for example, to connect a USB cable of a PC, tablet PC, smartphone, laptop, server, USB stick, etc., but the invention is not limited to such a connection. For example, a Bluetooth connection, a wireless connection, etc., may be provided as a wireless connection, but the invention is not limited to the examples of wireless connectors mentioned above.

The external electronic device 37 such as a smartphone, server or tablet PC, etc., may have a GPS device 101, a timing device 102, a camera device 103, a storage device 104, a transmitting device 105, a receiving device 106, a scanner device 107 and/or a microphone device 108 which may or may not be used with the measuring device 100.

Optionally, the measuring device 100 may also have at least its own storage device 111 for storing or interim storage, for example, of measuring data or measuring signals, etc. The storage device 111 may be accessed by the external electronic device 37.

The radiation receiver of the measuring device 100 may be connected to an evaluation device 109 of the external electronic device 37 in order to transmit the signals or data of the radiation receiver to the evaluation device 109 wirelessly or wired; for example, the signals or data of the radiation receiver for the analysis of the luminescent sample are evaluated in the evaluation device 109 of the external electronic device 37; the results of the evaluation may be displayed on an evaluation device 110, e.g. a display or screen displaying the external electronic device 37; and the signals or data of the radiation receiver 100 may also be stored in a storage device 104 of the external electronic device 37.

Furthermore, the measuring device 100 described above may have an optional additional microcontroller 34 and/or be coupled to such a microcontroller of an external device 37; the microcontroller 34 may be used, for example, to control and/or regulate the illumination of the respective lighting device and/or to control and/or regulate the sensitivity of the radiation receiving device, etc. For example, the microcontroller 34 may control the illumination duration, the illumination intensity, the illumination interval of the lighting device and/or the luminance of the lighting controller, etc. However, the invention is not limited to the above examples. This is true for all forms of measurement of the invention. The measuring device 34 may also be used together in a sample of the lighting device 50 or in a sample of the lighting medium 100 to approximate the measuring device.

Likewise, the measuring device 100 as described above may optionally have at least one separate storage device 111, an energy source 11, an analogue/digital converter 20 and/or a switch device 38 to turn the measuring device 100 on and off in addition to the measuring device 111.

Figure 9 shows a diagram of a measurement data system. The measurement data system has a first electronic device 137 such as a server, a PC, a smartphone or a tablet PC, several second electronic devices 37, especially smartphones or tablet PCs, and several measuring devices 100. The first electronic device 137 is wirelessly and/or wired to the second electronic devices 37 as described earlier in the example illustration in Figure 1 and forms a measuring and targeting device 115 with the second electronic device 37 having a receiving device to receive data or data etc. The measuring device 100 and the second electronic device 137 can transmit a wide range of electronic signals via the second electronic device 37 or 100 and transmit their values to the first electronic device 137 and the second electronic device 137.

The second electronic devices 37 are each capable of being connected wirelessly and/or wired to one or more associated measuring devices 100 as described above with reference to the example in Figure 1 and the examples in Figures 2-8.

The measuring instrument 100 is designed as a spectrometer or a measuring instrument to measure or analyse luminescent samples. Such measuring instruments 100 have been described previously by the example in Figures 1-8. The measuring instrument 100 is used to measure or analyse a sample in situ, for example a water sample from a well in Africa. The measuring data, for example analogue and/or digital signals from the measuring instrument 100, are transmitted from the measuring instrument 100 to the second electronic device 37 assigned to it and received by its receiver, for example wirelessly via a Bluetooth or radio interface or via a USB cable connection, for example.

The second electronic device 37 can evaluate the measurement signals, for example, in its evaluation device and transmit them to the first electronic device 137, for example, a central server in Germany, e.g. wirelessly, e.g. by means of a radio interface via a satellite.

The first or higher electronic unit 137 may store and reuse the results of the evaluation of the measuring instrument 100 for e.g. management, testing, evaluation, etc. Furthermore, the results of the evaluation or testing may be accessed from the central server, for example, by other electronic units, e.g. in environmental authorities worldwide.

The second electronic device 37 may, as described above with reference to Figures 1-8, evaluate not only the measuring device's signals or measuring signal in its measuring device, but may also have, in addition to or as an alternative to the measuring device, a GPS device, a timing device, a camera device, a storage device, a scanner device, an indicator device, a transmitter device, a receiver device and/or a microphone device which may be used with the measuring device 100.

This allows, in addition to the measurement data, in particular the analogue and/or digital signals of the measuring device, additional information or data from the GPS device, the timing device, the camera device, the scanner device, and/or the microphone device, etc., to be assigned and transmitted to the first or higher electronic device, for example by means of the transmitting device.

For example, the geographical position of a measurement made by the measuring instrument 100 may be determined by the GPS device and transmitted as additional information or data to the first electronic device 137. The same applies to the determination of the time and/or duration of a measurement made by the measuring instrument 100. This information or data may be determined by the measuring instrument 100 and transmitted as additional information or data to the first electronic device 137. Similarly, for example, a code of a batch number of a substance used for measurement or analysis may be scanned by the scanning device and transmitted as additional information to the first electronic device 137. Furthermore, for example, photographs of the location at which a measurement was made by the measuring instrument 100 may be recorded and transmitted to the first electronic camera 137 and the first electronic device 137.

The first electronic device 137, e.g. a central server, can store all this information and optionally further manage or evaluate it. For example, the electronic device 137 can determine from the scanned batch number code whether the expiry date has been complied with, the correct substance was used to perform the measurement, which measurement has been performed, e.g. a pH measurement, etc. The data from the timing device can be used to determine, for example, whether the measurement time has been complied with by the measuring device, etc. The GPS data can also be used to determine whether the measurement has been made at the correct location, etc. Measurements can be reliably monitored and controlled and the monitoring of the distance can be simplified considerably.For example, the GPS function can automatically determine the precise position data for the measurement. Furthermore, for example, information or data can be transmitted from the first electronic device 137 to the second or subordinate electronic device 37 and received by the receiving device of the second electronic device 37 at a wireless interface, e.g. a Bluetooth or radio connection. For example, the first or subordinate electronic device 137 can notify the second or subordinate electronic device 37 if there is a measurement error because, for example, the expiry date of the measurement substance used has been exceeded, the wrong substance was used for the measurement,the measuring time was not observed and/or the measurement was made at the wrong place; likewise, the first or parent electronic device 137 may also instruct the second or parent electronic device which measurement or measurements are to be made.

Although the present invention has been described above by reference to the preferred embodiments, it is not limited to these but can be modified in a variety of ways.

The term 'light' in this description includes both light visible to man and light outside the visible range, depending on the function and purpose of the light source or lighting device and the type of luminescent sample.
