This paper proposes an algorithm for processing measurement data of the temperature dependence of electrical conductivity of a SnO2-based gas sensor in order to determine the concentrations of individual components in C3H8-H2 and H2-CH4 mixtures. For this purpose, the sensor was calibrated for hydrogen, methane, and propane using metrologically reliable gas mixtures in dry air; the obtained concentration dependences were used to determine the coefficients of cross-sensitivity of the sensor to a particular component of the gas mixture. Using the well-known independent component method, linear equations were compiled for the studied two-component gas mixtures, the solutions of which satisfactorily describe the sensor signals obtained in the experiments. Keywords: electrical conductivity, adsorption, gas sensor, semiconductor, selectivity.
