Abstract
A method for carrying out analyses of a gas comprising one or more species Si, Sj, . . . , Sn by using of ion mobility spectrometry includes in carrying out two subsequent analyses in different conditions and comparing the results of these two analyses. The different conditions in the two analyses are such as to modify either the residence time of the ions corresponding to the species in the reaction zone or in the drift zone of the ion mobility spectrometer, or, selectively, the concentration of at least one of these ions.
