CRYO-1 and - CYRO-2 Cryogenic Sistemler

The capabilities of cryoluminescence techniques are implemented using cryogenic CRYO-1 and CRYO-2 systems. The CRYO-1 cryospectral system (shown in the picture) contains a FLUORAT®-02-2M analyzer, cryogenic unit, and a spectral analysis unit (an LM-3 monochromator), which are connected via fiber optic bundles. The cryogenic unit, where a substance under study is cooled to the liquid-nitrogen temperature (77 K), consists of a rack, Dewar vessel, and device for the uniform feed of samples for measuring (maximum of 12 simultaneously cooled samples). The CRYO-1 system is designed for determination of mass concentration of benz[a]pyrene in various objects from quasi-line fluorescence spectra due to the Shpol'skii effect. Using this technique, a high sensitivity and selectivity of the analysis are obtained.
The CRYO-2 cryospectral system comprises a FLUORAT®-02-2M analyzer and a cryogenic unit, which are also connected with each other via fiber optic bundle. The CRYO-2 is designed for measuring concentration of lead in samples of drinking, natural, and wastewater, and in food products. The analytical techniques are based on measuring the intensity of luminescence of lead chloride complexes in solutions at a temperature of 77 K, from which the lead concentration using a calibrated FLUORAT®-02-2M analyzer is measured. In addition, Bi, Te, and Se can also be detected. These techniques are high-sensitive and need very simple sample preparation.
