Abstract

L'invention concerne un spectromètre de masse qui comprend une source d'ions, un pré-filtre de masse statique en aval de la source d'ions, une cellule de collision en aval du pré-filtre de masse statique, au moins un analyseur de masse en aval de la cellule de collision, et au moins un détecteur d'ions en aval du ou des analyseurs de masse. Le préfiltre de masse statique (20) comprend une première unité de secteur magnétique (21) pour séparer des ions en faisceaux d'ions partiels (2), une seconde unité de secteur magnétique (22) pour fusionner les faisceaux d'ions partiels, et une fente (23) disposée entre la première unité de secteur magnétique et la seconde unité de secteur magnétique pour laisser passer sélectivement des faisceaux d'ions partiels (2). Les faisceaux d'ions partiels (2) peuvent être symétriques par rapport à un plan (S) perpendiculaire aux faisceaux d'ions partiels.
