Title
(EN) METHOD FOR CARRYING OUT ION MOBILITY SPECTROMETRY ANALYSES
(FR) PROCEDE PERMETTANT D'EFFECTUER DES ANALYSES PAR SPECTROMETRIE DE MOBILITE IONIQUE
Abstract
(EN)
Methods for carrying out analyses of a gas comprising one or more species Si, Sj, …, Sn by means of ion mobility spectrometry consisting 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 said 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.
(FR)
L'invention concerne des procédés permettant d'effectuer des analyses d'un gaz comprenant une ou plusieurs espèces Si, Sj, , Sn au moyen de la spectrométrie de mobilité ionique et consistant à effectuer deux analyses subséquentes dans des conditions différentes et à comparer les résultats de ces deux analyses; les conditions différentes dans les deux analyses sont telles qu'elles modifient soit le temps de résidence des ions correspondant aux espèces dans la zone de réaction ou dans la zone de dérive d'un spectromètre de mobilité ionique, soit, de manière sélective, la concentration d'au moins un de ces ions.
