Abstract

On présente un spectromètre de masse comportant une cellule de collision en phase gazeuse, une cellule de réaction ou une cellule de refroidissement collisionnel (1) comptant une série d'électrodes (2). On applique de manière progressive des différences de potentiel en courant continu à la cellule (1), de manière à ce que les ions sont précipités dans celle-ci.
