ABSTRACT:
A mass spectrometer is disclosed comprising an AC or RF ion guide having a plurality of plate electrodes and an upper plate electrode and a lower plate electrode. One or more channels are formed within the plate electrodes so that an ion guiding region is formed within the ion guide. The channels and hence the ion guiding region may be curved.
