Abstract: FIELD: gas analysis. SUBSTANCE: invention can be used for analysis of such gases as CO 2 •SO 2 NO and so on in gas mixture formed as result of burning of fuel in industrial plants, boilers of thermal power stations, boiler plants, etc. Process is carried out by reception of optical radiation passed through gas mixture with measurement and reference channels which number corresponds to number of sought-for gases in gas mixture. Spatial positions of optical inputs of measurement and reference channels for each sought-for gas is fixed during radiation reception in first time interval, then spatial positions of measurement and reference channels are so changed that optical inlet of measurement channel occupies spatial position of optical input of reference channel and vice versa. Then optical radiation passed through gas mixture during second measurement time interval is received and concentration of sought-for gas is determined by output signals of measurement and reference channels received during two time intervals. Spatial positions of optical inputs of measurement and reference channels are changed by attachment of photoelectric receivers of each channel to disc set on shaft of motor by their displacement through angular distance equal to 180 deg relative to each other. EFFECT: improved reliability of process and gear. 2 cl, 2 dwg
