FIELD: measurement equipment.
SUBSTANCE: analysed gas mixtures are sent via a gas analyser with sensors installed in it, electric signals are measured with the help of sensors, using calibrating functions produced on gas mixtures of available composition, values of concentrations of individual gas mixture components read by every sensor are determined, additional measurement of electric signals from sensors is carried out, during realisation of which chemical filters are installed at inlets of sensors, and the filters separate from a gas mixture arriving to each sensor the individual component of the gas mixture determined by this sensor, gas mixtures without individual components are sent via sensors, electric signals are measured with the help of sensors, which correspond to gas mixtures in absence of these individual components, and then the difference is determined between electric signals produced from sensors in presence of individual components of the gas mixture determined by each sensor, and in their absence, and with usage of calibration functions produced on gas mixtures of available composition, by values of these differences of electric signals they determine actual values of concentrations of individual components of the gas mixture, determined by each sensor. Also a gas analyser is proposed for realisation of the above method.
EFFECT: higher validity of analysis due to exclusion of distorted impact of components available in a gas mixture, which are not individual ones determined by each sensor, at accuracy of determination of gas composition.
