Patent

CA 2667444

A mass spectrometer is disclosed comprising an ion mobility spectrometer (8) and an ion gate (9). A collision cell (10) is arranged downstream of the ion gate (9). The operation of the ion mobility spectrometer (8) and the ion gate (9) are synchronised so that only ions having a particular mass to charge ratio and a desired charge state are onwardly transmitted to the collision cell (10).

L'invention concerne un spectromètre de masse comprenant un spectromètre à mobilité ionique (8) et une grille ionique (9). Une cellule à collision (10) est disposée en aval de la grille ionique (9). Les fonctionnements du spectromètre à mobilité ionique (8) et de la grille ionique (9) sont synchronisés de telle sorte que seuls les ions présentant un rapport masse sur charge particulier et un état désiré de charge sont transmis en avant à la cellule à collision (10).
