Abstract:
A closed-loop ion guide is disclosed comprising a plurality of electrodes having apertures through which ions are transmitted in use. Ions are injected into the closed-loop ion guide and may make several circuits of the closed-loop ion guide before being ejected from the ion guide. In a mode of operation the ion guide may be arranged to separate ions temporally according to their ion mobility.
