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.
