Abstract
A mass spectrometer is disclosed comprising a FAIMS device comprising two parallel electrodes () in series with an ion mobility separator () forming part of a mass spectrometer. Ions are separated in the FAIMS device () according to their rate of change of ion mobility with electric field strength. The ions which are onwardly transmitted from the FAIMS device () are then passed to an ion separator device () comprising a plurality of electrodes () and an optional ion trapping region (). Ions are radially confined with the ion separator by application of an AC or RF voltage to the electrodes () and ions are separated according to their ion mobility by applying an axial DC voltage gradient which may remain constant as a function of time or which may vary with time.
