Abstract

The present invention pertains to the field of analytical chemistry and relates to a utility model which can be used in laboratory conditions for carrying procedures of quantitative chemical analysis in the fields of ecology, industrial hygiene, clinical diagnosis and industrial survey. The model of the present invention is used for increasing the functional capacities of an already-existing device by providing said device with an extended spectrum, a highly stable sensitivity as well as a simple and compact structure. To this end, the fluorimeter comprises a light source which is optically connected through a lens to an excitation optical filter. The fluorimeter also includes a vessel optically connected to a recording optical filter as well as a recording system. The light source is a pulsed one while the recording system comprises three channels each including a photo-receptor which is connected to a strobing integrator, wherein the outputs of said integrators are connected to an analog-digital converter. One of the photo-receptors is connected through a buffer amplifier to the analog-digital converter which is in turn connected through a control device to an indication device. The strobing integrators are connected to a measuring-pulse formatter which is in turn connected to the control device. The fluorimeter further includes two light-dividing plates one of which is optically connected to the excitation optical filter while the other is connected to a focusing system.
