OPTICAL ABSORPTION GAS ANALYZER Russian patent published in 2022 - IPC G01N21/61 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring technology and concerns an optical absorption gas analyzer. The gas analyzer contains electromagnetic radiation sources and light filters with wavelengths from the absorption region of the analyzed gases, cuvettes, photodetectors and a computer with a trained neural network. The sources of electromagnetic radiation are located in a circle of the radiation input node in the cuvettes. The cuvettes are made in the form of capillary fibers with an external reflecting surface along the length, and the lengths of the cuvettes are equal to the value of the inverse value of the absorption coefficient of the gas under study multiplied by the inverse ratio of the signal to the noise of the system. The photodetectors at the output of the cuvettes are connected to amplifiers and analog-to-digital converters, which in turn are connected to a module of a trained neural network.

EFFECT: increase in the versatility, informativeness, sensitivity and accuracy of measurements.
