METHOD FOR DETERMINING GAS MIXTURE COMPONENTS Russian patent published in 2023 - IPC G01N21/61 

FIELD: measuring technology.

SUBSTANCE: invention can be used to create high-speed portable devices for identifying gases. The method for determining the components of a gas mixture consists of generating wavelengths of electromagnetic radiation in the absorption region of the analysed gas components, passing the generated waves through gas cells, and recording the generated waves at the exit from the cells. The method is characterized by the fact that sources and receivers of electromagnetic radiation are placed in a circle around the unit for introducing radiation into cuvettes, and the cuvettes are made in the form of capillary fibres with an internal reflective surface. The concentrations of the j-th component in the form of an optical signal from the output of each cuvette are transmitted to photodetectors, amplified and transmitted through analogue-to-digital devices to a pre-trained neural network module.

EFFECT: increased versatility, information content, sensitivity and accuracy of measurements.
