摘要：

A simple model of the sensor behaviour based on reaction kinetics was created. The SnO2 sensor is operated in the dynamic regime. The properties of the designed model were verified by means of experiments. The experiments were carried out with organic liquid vapours in air (ethanol, acetone, benzene, hexane) and three different types of gas sensors TGS 813, TGS 822, SO 91 K. The properties of the described model enable the gas concentration to be determined and may possibly be used for substance discrimination. © 2004 Elsevier B.V. All rights reserved.
