AUTOMATED SPECTROMETER FOR THE STUDY OF LIQUID MEDIA Russian patent published in 2023 - IPC G01J3/02 G01N21/63 

FIELD: optical instrumentation.

SUBSTANCE: automated spectrometer for analysing liquids. Spectrometer consists of a control and analysis unit equipped with a Wi-Fi antenna, an optical unit, a liquid supply pipeline, a flow and measuring cell, connected by a detachable coupling. The control and analysis unit is based on a microcomputer and includes a CCD matrix, a monochromator, and a battery. The optical block contains an ND:YAG laser with an optical focusing system. The flow cell contains an aerosol generator. The measuring cell is equipped with a ventilation system that ensures the performance of the aerosol generator is equalized with the performance of the ventilation system, a quartz window for introducing laser radiation, and a system for focusing stimulated radiation at the input of an optical fibre connected to the monochromator of the control and analysis unit.

EFFECT: increased detection sensitivity and reproducibility of results, as well as automation of measurements.
