The concentration of oxidising gases such as NO2, NO, Cl2, O3 in a gas mixture is determined by pertubing the operating conditions of a semiconductor gas sensor; the pertubation may be a temperature change or a change in concentration of the gas; the invention is particularly suited to ozone sensing with tungstic oxide sensors.
