Abstract

A method determines a potential poisoning of a sensor of an electronic nose by a volatile compound following an exposure of the sensor to a gaseous sample including at least this volatile compound. If there is poisoning, the method determines whether the sensor is still functional such that the sensor is still capable of carrying out one or a plurality of reliable measurements, or on the contrary, whether the sensor is saturated and must no longer be used. The method may be used with any type of electronic nose.
