Abstract

A mass spectrometer is disclosed comprising an ion guide 15 which spans two or more vacuum chambers 18,19.
The ion guide 25 comprises a plurality of electrodes having apertures. Preferably, one of the electrodes 8 may also form the differential pumping aperture which separates two vacuum chambers 18,19.
