ABSTRACT:
A mass spectrometer is disclosed having an ion guide which receives ions from either a pulsed ion source or an ion trap, or a continuous ion source. The ion guide emits packets of ions. The pulses of ions emitted from the ion guide may be synchronised with another device such as an ion detector, an orthogonal acceleration Time of Flight mass analyser, an ion trap or a mass filter.
