Description

  The present invention relates to a draft and an analysis vehicle equipped with the draft.

  In recent years, the use of immunoassays as a quantitative analysis technique for target substances (for example, harmful substances) is gradually increasing. Since the immunoassay utilizes the specificity of the antibody for the antigen, the target substance can be obtained without causing much binding to a substance having a structure or property similar to that of the target substance as compared with other analytical methods. It can be detected with high sensitivity. Further, the immunoassay requires a short time to detect a target substance, and can detect the target substance quantitatively using various detection devices by using an antibody labeled with a labeled compound. Because of these various advantages, immunoassays are actually being used or are being considered for use.

  Various facilities and equipment have been developed in laboratories and laboratories to meet the requirements for avoiding contamination of the analyte, stable conditions for antigen-antibody reaction, and detection of the analyte after the reaction. . In general, immunoassays are carried out by transporting analytes to research facilities and laboratories. However, as the opportunity to use immunoassays increases, it must be able to be carried out in an environment that is not fully equipped (for example, outdoors and places designated by the client where it is difficult to carry the analyte). It came to be able to.

  Therefore, a mobile analysis system in which analysis equipment is mounted on a vehicle has been proposed (for example, Patent Documents 1 and 2). These analysis systems can provide an analysis environment similar to the analysis in a facility in various places by mounting sufficient facilities on a large vehicle.

Japanese Utility Model Publication No. 6-47844 (released June 28, 1964) JP 2002-350421 A (released on December 4, 2002)

  However, the techniques of Patent Documents 1 and 2 require a container or truck bed having a large space in order to mount equipment designed for use in a facility. Therefore, when the vehicle cannot pass on the way to the analysis site because of the total length, height, or width of the vehicle, or the parking space cannot be secured and the analysis cannot be performed near the location where the analysis target is collected. Can occur.

  Some of the equipment required for immunoassays must be relatively large. In particular, a draft for performing a pretreatment for collecting a test object and subjecting it to an immunoassay requires a space in which a person performs work after storing a large number of instruments and tools. Further, the draft needs to prevent the internal gas from staying depending on the reagent used. For this reason, in order to function sufficiently as a draft, at least an exhaust port for discharging the internal gas and a duct connected to the exhaust port are necessary. Therefore, a space for the duct forming part must be secured in the draft arrangement. Conventional drafts are generally designed on the basis of use in a facility, and no consideration is given to space saving.

  In view of the above problems, an object of the present invention is to provide a draft of a size that can be mounted on various automobiles.

  In order to solve the above problems, the draft of the present invention is a draft that includes a chamber and a suction port that draws fluid from the inside of the chamber, and the suction port is formed on the bottom surface of the chamber. Below the bottom surface, a filter that adsorbs some components contained in the fluid is provided in communication with the suction port.

  In the draft, the chamber is preferably shut off from the outside by an opening / closing portion and a fixed partition that are divided into a plurality of panels, and all of the plurality of panels are preferably movable relative to each other.

  In the draft, the opening / closing part is preferably opened / closed by the parallel movement or folding of the panel.

  In the draft, the filter preferably contains activated carbon.

  The draft preferably further includes adjusting means for adjusting the height of the chamber.

  Moreover, it is preferable that the said draft is further provided with the base which has a movable part which enables conveyance.

  In the draft, it is preferable that the partition wall has an closable opening for adjusting the flow rate of the fluid.

  The draft further includes control means for controlling the flow rate of the fluid drawn from the suction port, below the position where the activated carbon filter is provided so as to communicate with the suction port and the adsorbent. It is preferable.

  In order to solve the above problems, the analysis vehicle of the present invention includes the above-described draft.

  Moreover, it is preferable that the analysis vehicle has a height of 110 cm or more and 185 cm or less inside the vehicle.

  Further, in the analysis vehicle, it is preferable that a region maintained at a constant temperature and a region where the draft is disposed are separated.

  In the analytical vehicle, it is preferable that the region maintained at a constant temperature is formed inside the thermostatic chamber.

  In the analysis vehicle, the region maintained at a constant temperature and the arrangement region of the draft are preferably separated by a partition in the vehicle.

  The present invention has an effect that it is possible to provide a draft that can be mounted not only on a large-sized or medium-sized vehicle but also on various vehicles.

  Embodiments of the present invention will be described below with reference to the drawings.

[Draft 1]
A draft 1 according to an embodiment of the present invention will be described below with reference to FIG. FIG. 1A is a front view showing an embodiment of the draft of the present invention, and FIG. 1B is a top view showing the inside of the draft.

  As shown in FIG. 1A, the draft 1 includes a slide panel (opening / closing part) 11, a fixed panel 18, a chamber 12, a support part 19, a filter (activated carbon) 13, a leg part 14, and a base part 15. . As shown in FIG. 1B, the draft 1 further includes a work table 16 and a work table 17. A duct (not shown) connected to the fan is connected to a portion protruding downward from a space indicated by a broken line outside the support portion 19 (FIG. 1A), and the inside of the chamber 12 Gas is exhausted through the duct. That is, the draft 1 of the present invention is a draft capable of performing an experimental operation on the work table 16 and the work table 17 without causing gas to stay in the chamber 12. However, the draft 1 of the present invention is different from the draft used in the facility (hereinafter referred to as “normal draft”) so that it can be mounted (reduced in size) in various vehicles without impairing the original function. In addition, various improvements have been made. Details of the main configuration and improvements of the draft 1 of the present invention will be described below.

(Slide panel 11)
The slide panel 11 is composed of two slide-type panels 11a and 11b. The panel 11a slides upward, and the panel 11b slides downward. That is, the slide panel 11 functions as a doorway that opens and closes in the vertical direction for human hands and instruments in the chamber 12. The slide panel 11 contributes to downsizing of the draft 1 as follows by opening and closing in the vertical direction. In the following, when the downsizing of the draft 1 is described, the case where the draft 1 is mounted on a wagon type ordinary automobile or the like will be described as an example unless otherwise specified.

  In a normal draft, only the lower panel is slid upward to secure the entrance. A normal draft is large because it is designed for indoor use, and can take a large area of the lower panel. Therefore, if the lower panel is pulled upward, the instrument can be easily put inside. However, a normal draft cannot be mounted on, for example, a wagon type ordinary car.

  When a tall instrument is placed in the chamber 12, the draft 1 is generally lower than a person's height, so even if the panel 11b is slid downward, it is not easy to move the instrument to tilt and lift from below. . Therefore, in such a case, it is easier to put the instrument down from above by pulling up the panel 11a. Moreover, an instrument can be easily carried in by opening the panel 11a and the panel 11b up and down. In this way, even if the area of the slide panel 11 (and hence the volume in the chamber 12) is designed to be small as necessary, it does not hinder the loading of the instrument. If only the panel 11b is pulled down without pulling up the panel 11a, human work is possible.

  The slide panel 11 is made of, for example, a transparent plate made of glass, acrylic resin, or vinyl chloride resin. The purpose of the transparency of the slide panel 11 is to allow the work in the chamber 12 to be visually confirmed.

(Workbench 16 and 17)
The work table 16 is provided on a part of the bottom surface of the chamber 12 (near the outer periphery of the side surface and the back surface), and a large number of holes are formed by punching (not shown). The gas in the chamber 12 is drawn out downward from the draft 1 through the numerous holes. That is, a large number of holes serve as gas inlets. The work table 17 is configured as a flat plate. The large number of holes in the work table 16 contributes to the downsizing of the draft 1 as described below.

  The normal draft is connected to, for example, a duct (that is, a position higher than the draft) arranged behind the ceiling. Depending on the type of volatile solvent handled in the chamber 12, in a normal draft, it is often preferable to suck the gas from the top of the chamber because the gas is sent above the draft. That is, a normal draft often requires a space for providing an exhaust port and a duct in the upper part of the chamber. However, when installed in a relatively small automobile, there is almost no extra space, so the usual draft configuration is inconvenient.

  As described above, in the draft 1 of the present invention, the gas in the chamber 12 is drawn from the hole of the work table 16. Therefore, the gas in the chamber 12 can be properly drawn out even if there is no room above the chamber 12. The draft 1 has a height of, for example, about 1500 mm in accordance with the height inside the vehicle. Therefore, when the volume of the chamber 12 is secured to such an extent that a person can work, a space enough for a person's foot to enter cannot be secured below the support base 19. Therefore, the draft 1 can be reduced in size without generating a useless space by using the lower space as an arrangement location for exhausting the space.

  Here, a configuration in which a large number of holes are formed in the work table 16 is described as an example. However, the work table 16 only needs to be formed so that gas can pass from the inside of the chamber 12 to the lower part. For example, when the work table 16 is made of a mesh-like member, a large number of slits may be formed.

(Filter 13)
The filter 13 is disposed below the bottom surface of the chamber 12 (work table 16 and work table 17). The filter 13 adsorbs harmful substances (organic solvent, acid, etc.) contained in the gas drawn out from a number of holes in the work table 16. The filter 13 contains activated carbon as a medium for adsorbing harmful substances. Since the filter 13 is disposed below the bottom surface of the chamber 12 and contains activated carbon as a medium to be adsorbed, it contributes to the downsizing of the structure necessary for the function of the draft 1 and the draft 1 as described below. ing.

  As described above, since the gas in the chamber 12 is drawn out from a large number of holes in the work table 16, the arrangement of the filter 13 through which the gas is passed is an arrangement for eliminating useless piping. In addition, activated carbon as a medium that adsorbs harmful substances is easier to pass gas (pressure loss is small) than other filter materials. Therefore, the necessary flow rate of gas can be ensured by using the fan 25 with low power consumption (output). Since a generator having a large size and power is required in proportion to the amount of power consumed by the fan, the fan 25 and the generator can be downsized by using the filter 13.

  The activated carbon used for the filter 13 is granular, powdery, plate-like or solidified from powder, etc., depending on the type of substance to be adsorbed, other configurations in the draft 1, and the configuration required for the function of the draft 1 It can take a variety of forms. Here, activated carbon is mentioned as the adsorbent of the filter 13, but any adsorbent (for example, a HEPA filter (high-efficiency particulate air filter) or the like) that can realize suitable adsorption of harmful substances and small pressure loss. There is no particular limitation.

  In a normal draft, exhaust is passed through a duct of the facility and exhausted from an outdoor chimney or the like. The exhaust from the draft 1 of the present invention is exhausted from the side surface (window or door) of the vehicle when used on a vehicle. For this reason, the draft 1 requires a configuration for removing harmful substances. That is, the filter 13 is essential for the draft 1 of the present invention.

  As described above, the draft 1 of the present invention has various improvements added to the slide panel 11, the work table 16, and the filter 13. Therefore, the draft 1 is much smaller than a normal draft and can be used in a vehicle. There are many types.

  In the above, the main structure which contributes to size reduction of the draft 1 was demonstrated. Other configurations to which improvements are added are described below.

(Other configurations)
The draft 1 includes fixed panels 18 on the upper surface, side surfaces, and rear surface. The fixed panel 18 can be made of the same material as the slide panel 11. A part of the fixed panel 18 may be provided with an closable opening. The closable opening may be configured to include, for example, a sliding panel that covers the opening. When the opening degree of the chamber 12 (the degree to which the panel 11b is pulled down) is small as compared with the suction force of the fan 25, the flow velocity in the chamber 12 becomes extremely large. When the flow rate is extremely large, there is a possibility that the operation in the chamber 12 may be hindered. Therefore, in such a case, if the opening in the fixed panel 18 is opened, a desired flow rate can be maintained.

  The draft 1 includes leg portions 14. The leg portion 14 preferably has a movable part that can be expanded and contracted vertically. For example, if the entire leg portion 14 is formed as a jack, the height of the chamber 12 can be freely changed.

  The draft 1 has a base 15. It is preferable that a caster or the like is provided in the lower portion of the base portion 15. This is because the draft 1 can be taken out of the vehicle or transferred from one vehicle to another as necessary. When a structure for moving the draft 1 such as a caster is attached to the base portion 15, it is preferable that a stopper for temporarily fixing the draft 1 is attached at the same time. This is to prevent the draft 1 from moving when the vehicle carrying the draft 1 is traveling.

  As described above, the draft 1 of the present invention is optimized not only for miniaturization but also for in-vehicle use by various improvements.

[Draft 1 ']
A draft 2 according to another embodiment of the present invention will be described below with reference to FIG. FIG. 2A is a front view showing another embodiment of the draft of the present invention, and FIG. 2B is a top view showing the inside of the draft. Note that the description of the configuration having the same features as the draft 1 of FIG. 1 will not be repeated.

  As shown in FIG. 2A, the draft 1 ′ includes a folding panel (opening / closing part) 11 ′, a fixed panel 18, a chamber 12, a support part 19, and a filter 13. As shown in FIG. 2B, the draft 1 ′ further includes a work table 16 and a work table 17. A duct (not shown) connected to the fan is connected to a vertical portion at the lower left of the space indicated by the broken line outside the support 19 (FIG. 2A), and the chamber 12 The gas inside is exhausted through the duct.

  The draft 1 ′ is mainly different from the draft 1 in that the folding panel 11 ′ is provided and the positions of the work table 16 and the work table 17 are reversed.

  The folding panel 11 'includes panels 11'a and 11'b. The panel 11'a is attached to the fixed panel at the top by a spring and a hinge so that the front surface of the panel 11'a and the front surface of the fixed panel at the top thereof are opposed to each other. The panel 11'b is attached to the panel 11'a by a spring and a hinge so that the back surface of the panel 11'b and the back surface of the panel 11'a face each other. Therefore, when the panel 11 ′ b is moved upward, the panel 11 ′ a and the panel 11 ′ b are folded and moved to the front side of the fixed panel at the top. Therefore, the folding panel 11 ′ can be opened to the extent that a person can work in the chamber 12 without protruding above the draft 1 ′. Since the inside of the chamber 12 can be sufficiently visually recognized by opening the panel 11'a and the panel 11'b, the panel 11'a and the panel 11'b may not be transparent.

  In the draft 1 ′, the work table 17 is located on the outer periphery on the bottom surface of the chamber 12, and the work table 16 is located on the inner side. A filter 13 having substantially the same area as the work table 16 is disposed immediately below the work table 16. The structure opposite to that of the draft 1 is that the work table 16 provided with a large number of holes for drawing out the gas in the chamber 12 and the region connected to the duct (the broken line inside the support portion 19). This is because the area is almost the same, so that it is efficient for gas extraction and harmful substance adsorption.

  The draft 1 'is a fixed draft that does not include a leg portion and a base portion. In order to pass a vehicle inspection as a special vehicle (for example, an ambulance, a fire engine, etc.) using a vehicle equipped with the draft 1 ′, it is necessary to make the draft stationary. Therefore, when manufacturing a vehicle approved as a special vehicle, a fixed draft 1 'is preferable.

  A volume damper is provided in a region connected to the duct (broken line outside the support portion 19) directly or via the duct. By opening or restricting the flow path in the volume damper, the flow rate in the chamber 12 can be set to a desired range. In addition, although the bottom face of the area | region connected to a duct is flat here, it can be formed as a surface which the left side in drawing is low and the right side has a high inclination. The degree of the inclination can be appropriately determined so that the flow velocity in the whole of the plurality of holes in the work table 16 is approximately constant.

  The fixed panel 18 on the upper surface of the draft 1 'may further include a lighting fixture (not shown). Since the inside of the chamber 12 is brightened by using the lighting device, the operation is facilitated. The luminaire and the fan 25 can be turned on / off by switching the same or different switches.

  As described above, the draft 1 ′ is much smaller than a normal draft and is optimized for use in a vehicle by various improvements as described above. Although there are different configurations for each of the draft 1 and the draft 1 ′, it will be apparent to those skilled in the art that they can be applied to each other as long as no inconvenience occurs.

[Analysis vehicle 20]
An analysis vehicle 20 according to an embodiment of the present invention will be described below with reference to FIG. FIG. 3 is a diagram showing the internal arrangement of the analytical vehicle according to one embodiment of the present invention.

  As shown in FIG. 3, the analytical vehicle 20 includes a draft 1, a centrifugal evaporator 23, a thermostatic chamber 21, a syringe pump 22, a computer 24, and a fan 25. In other words, the analytical vehicle 20 includes equipment and equipment capable of performing an immunoassay.

  The draft 1 is connected to the fan 25 through the duct as described above, and can exhaust the gas in the chamber 12. A duct is further connected to the fan 25, and the gas from the chamber 12 is exhausted outside the vehicle. In the draft 1, a component containing the target substance is eluted from the analysis target sample.

  The fan 25 is installed so that it can be taken out of the vehicle. Conditions required for the fan 25 include a control wind speed of 0.4 m / s or more and acid resistance. Therefore, the fan 25 is not particularly limited as long as the above conditions are satisfied.

  The centrifugal evaporator 23 is connected to a vacuum pump (not shown), and is a device that removes a volatile solvent by centrifugation under reduced pressure conditions and concentrates the above components. The conditions required for the centrifugal evaporator 23 are that a pitch tube having a capacity of 14 mL can be processed at a rotational speed of 100 rpm or more and 2000 rpm or less, and any centrifugal evaporator satisfying these conditions is not particularly limited. An exemplary centrifugal evaporator 23 is a centrifugal evaporator CVE-3100 (manufactured by Tokyo Rika Kikai Co., Ltd.). The vacuum pump is not particularly limited as long as it can be depressurized to a desired degree in the centrifugal evaporator 23. An exemplary vacuum pump is a diaphragm vacuum pump DTU-20 (available from ULVAC Kiko Co., Ltd.).

  The desk on which the centrifugal evaporator 23 and the computer 24 are mounted (shown by a broken line in FIG. 3) is preferably installed so as to be removable. This is because by taking the desk out of the vehicle, the space at the front of the draft 1 can be expanded, and the workability in the draft 1 can be improved.

  The syringe pump 22 is a device for pouring a liquid obtained by mixing the above components and an antibody and causing an antigen-antibody reaction from the syringe into a measurement cell. The syringe pump 22 is two types of syringe pumps that can discharge liquid from the syringe at an arbitrary flow rate. If it has the above performance, the kind of syringe pump 22 will not be specifically limited. An exemplary syringe pump 22 is a syringe pump IMP-1040 (manufactured by Shibata Kagaku Co.).

  The inside of the thermostatic chamber 21 is shut off from the outside, and the temperature inside the bath can be controlled with an error of ± 1 ° C. so as to be within a range of 20 ° C. to 25 ° C., for example. The thermostatic chamber 21 will be described below with reference to FIG. Fig.5 (a) is a front view which shows the thermostat 21 which concerns on one Embodiment of this invention, FIG.5 (b) is a top view which shows the said thermostat.

  As shown to Fig.5 (a), the thermostat 21 is provided with the operation part 21a, the control part 21b, and the operation | movement part 21c. The working unit 21a is provided with a tank that actually performs measurement whose temperature is controlled as described above. The control unit 21b includes a control panel for setting conditions such as temperature on an external front surface, and a configuration for performing electrical control such as a switchboard is housed inside. The operating unit 21c receives a control signal from the control unit 21b, operates an internal motor, etc., and operates to keep the temperature in the tank at a set temperature.

  As shown in FIG. 5B, the working unit 21 a includes a tank 32 and a blower unit 33. The air blowing unit 33 sends air at a constant temperature into the tank 32 in order to maintain the temperature in the tank 32 at the set temperature. As for the tank 32, the side surface is formed in the taper shape from the rear part to the front part. Accordingly, the hand receiving port 31 is not parallel, and the workability for the user is improved. Moreover, the upper surface (FIG. 5 (a)) of the tank 32 that is inclined downward from the rear part to the front part can be opened and closed in a flip-up manner, thereby facilitating the taking in and out of the equipment (for example, measuring instruments and measuring cells) Yes. The degree of the antigen-antibody reaction to be analyzed is quantitatively measured in the tank 32 maintained in a temperature range suitable for measurement.

  The computer 24 incorporates a program that takes in data acquired in the thermostatic chamber 21 and quantifies the target component contained in the analysis target. The computer 24 is preferably a notebook computer that does not require extra space for installation.

  Although not shown in FIG. 3, the analysis vehicle 20 further includes a refrigerator for storing a reagent (for example, an antibody) used for analysis. The analysis vehicle 20 further includes a generator. The generator is not illustrated because, for example, the generator can be disposed outside the vehicle at the analysis site and power can be supplied into the vehicle, so that it is not necessary to exemplify a particularly preferable position. In addition, it is preferable that the generator of the present embodiment is covered so that liquid droplets do not enter the inside so that the generator can be used outdoors in rainy weather. In order to suppress the size of the generator to be provided and reduce the number, it is preferable that the configuration that requires a power source among the above configurations has low power consumption.

  The analysis vehicle 20 preferably has a height of 110 cm or more and 185 cm or less inside the vehicle. If the height is 110 cm or more, it is possible to carry in equipment (especially draft 1) and work by humans. If the height is 185 cm or less, the analytical vehicle 20 can enter any place and can be parked. is there.

  The internal arrangement of the analysis vehicle 20 described with reference to FIG. 3 is merely an example, and various changes can be made according to the size of the selected vehicle and internal equipment. Further, it is obvious to those skilled in the art who have come into contact with the present specification that the configuration applicable to the analysis vehicle 20 among the configurations of the analysis vehicle 20 ′ according to other embodiments described later can be appropriately employed. is there.

  As described above, the analysis vehicle 20 of the present invention can perform an immunoassay at an arbitrary location (for example, a site where an analysis object is obtained or a location designated by a client).

[Analysis vehicle 20 ']
An analysis vehicle 20 ′ according to another embodiment of the present invention will be described below with reference to FIG. FIG. 4 is a view showing the internal arrangement of an analytical vehicle according to another embodiment of the present invention.

  As shown in FIG. 4, the analytical vehicle 20 includes a draft 1 ′, a syringe pump 22, a centrifugal evaporator 23, a computer 24, a cooling trap 26, a sink 27, and a generator 28. That is, the analytical vehicle 20 'is similarly equipped with equipment and equipment capable of performing an immunoassay. The analysis vehicle 20 ′ is an example of a design based on the fact that the space inside the vehicle is secured a little wider and all the components are fixed and approved as a special vehicle.

  A pump that draws the gas in the chamber 12 is connected to the lower part of the draft 1 ′ via a volume damper. By providing the volume damper, the flow rate of the gas drawn out from the chamber 12 can be controlled within a desired range.

  The cooling trap 26 is a device that efficiently collects the organic solvent exhausted from the centrifugal evaporator 23 under reduced pressure conditions and reduces the amount of vapor flowing into the vacuum pump. Therefore, the cooling trap 26 is connected to the centrifugal evaporator 23 and the vacuum pump. An exemplary cooling trap 26 is a desktop cooling trap UT-1000 (manufactured by Tokyo Science Instruments Co., Ltd.). Further, for example, a vacuum control unit for controlling the pressure in the centrifugal evaporator 23 by opening / closing an electromagnetic valve is attached between the vacuum pump and the centrifugal evaporator 23. An exemplary vacuum control unit is a vacuum control unit NVC-2200A (manufactured by Tokyo Rika Kikai Co., Ltd.).

  The sink 27 is configured to clean instruments used for analysis. In this embodiment, since all the configurations are fixed as described above, the generator 28 is arranged at a corner in the vehicle so as not to hinder the work.

  An air curtain (not shown) is provided between the work table on which the syringe pump 22, the centrifugal evaporator 23, and the cooling trap 26 are disposed and the draft 1 '. By partitioning the interior of the vehicle with the air curtain, the temperature on the side where the work table is installed is appropriately controlled, and conditions suitable for measurement of the analysis target can be easily maintained. The air curtain is a sheet made of, for example, vinyl chloride, but is not particularly limited as long as it is a material and a form that can control the temperature on the work table side while suppressing the amount of air blown to the draft 1 'side. A roof air conditioner (not shown) is provided as a temperature control device on the ceiling on the work table side in the analysis vehicle 20 '. Although another device can be adopted as the temperature control device, a roof air conditioner that can be arranged on the ceiling is preferable because it is easier to secure a space for arranging other components.

  As described above, the analytical vehicle 20 ′ of the present invention is manufactured from a fixed configuration, and can perform an immunoassay at an arbitrary location (for example, a site where an analysis target is obtained or a location designated by a client). is there.

[Example of analysis method]
As an example of the analysis method according to the present invention, a method for quantitatively detecting polychlorinated biphenyl (PCB) contained in the analysis target (insulating oil) in the analysis vehicle 20 will be described.

  First, the operation in the chamber 12 of the draft 1 will be described below. The sample insulating oil is loaded onto a high concentration silica gel column. After standing for a few minutes, pour the appropriate amount of hexane over the column twice. After standing for about 1 minute, pour a sufficient amount of hexane onto the column for elution. At this time, an appropriate amount of dimethyl sulfoxide (DMSO) is put in the column before adding hexane. When these operations are completed, the components (including PCB) contained in the insulating oil are eluted with hexane.

  Next, the column is placed in the centrifugal evaporator 23, the solvent is removed, and the above components are concentrated. Only the DMSO layer (in the lower layer) containing the above components is collected on the desk in the car (broken line in FIG. 3). This completes the pretreatment for performing the immunoassay.

  In the above-mentioned desk, the collected analysis object is mixed with an anti-PCB antibody labeled with colloidal gold. Let stand for about 1 hour to cause antigen-antibody reaction. After completion of the reaction, the reaction liquid is injected into the detection cell for measuring the absorbance of the analysis target using the syringe pump 22. Here, the detection cell is provided with a membrane that traps only the anti-PCB antibody not bound to PCB and allows the anti-PCB antibody bound to PCB to permeate. The detection cell into which the reaction solution has been injected is dried on the desk.

  During drying, an absorbance measuring device is placed in the thermostatic chamber 21 and the interior of the bath is maintained at 20 ° C to 25 ° C. After the drying is completed, the absorbance of the detection cell is measured, and the measurement data is sent to the computer 24 to determine the amount of PCB contained in the analysis target.

  Here, the method of quantitatively analyzing PCB contained in the analysis target has been described as an example, but the antibody to be used may be changed according to the target substance. Therefore, for example, various substances contained in food and outdoor water can be analyzed in the analytical vehicle 20 of the present invention moved to an arbitrary place.
