Abstract
A method is proposed for measuring the concentration dependence of the thin-layer gas sensor sensitivity in a dynamic mode using only one certified gas-air sample with an impurity concentration corresponding to the upper limit of the concentration range for which the calibration is performed. A decrease in the total time of the measurement run is an advantage of the method. The response speed of the sensor for ethanol vapor in air on the basis of a thin tin dioxide (SnO2) layer is investigated, and the concentration dependence of its sensitivity to ethanol vapor is presented.
