  • Time of flight ion trap tandem mass spectrometer system
    Patent number: 7183542
    Abstract: Apparatus for delivering ions to a mass analyzer. The apparatus includes a time of flight ion guide, a pulsing device for receiving a continuous ion stream containing ions of different atomic mass and for delivering pulses of ions to the ion guide wherein ions in each of the pulses of ions exit the ion guide in ascending order of their atomic mass, and a gating device at the exit end of the ion guide for allowing ions of a predetermined atomic mass to pass to the mass analyzer.
