    摘要: A mass spectrometer is disclosed comprising an ion beam attenuator which attenuates an ion beam repeatedly switching between a zero transmission mode of operation during a time period ΔT1 and a non-zero transmission mode of operation during a time period ΔT2. The degree of attenuation of the ion beam can be varied by varying the mark space ratio ΔT2/ΔT1. The ion beam attenuator may release ions in packets or pulses but the packets or pulses of ions may be converted into a continuous ion beam by a relatively high pressure ion guide or gas collision cell arranged downstream of the ion beam attenuator.

    摘要: A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator (4) and an ion guide (6) arranged downstream of the ion mobility spectrometer or separator (4). A plurality of axial potential wells are created in the ion guide (6) so that ions received from the ion mobility spectrometer or separator (4) become confined in separate axial potential wells. The potential wells maintain the fidelity and/or composition of ions received from the ion mobility spectrometer or separator (4). The potential wells are translated along the length of the ion guide (6).

    摘要: An ion guide or ion trap (1) is disclosed comprising a segmented linear ion guide or ion trap. Ions are confined radially within the ion guide or ion trap (1) by the application of an AC or RF voltage to the electrodes. A static potential well is maintained along at least a portion of the axial length of the ion guide or ion trap (1). A time varying homogeneous electric field is applied along at least a portion of the axial length of the ion guide or ion trap (1). The combination of the static axial potential well and the time varying axial homogeneous electric field causes ions to be ejected from the ion guide or ion trap (1) in a substantially non-resonant manner.

    摘要: An ion guide or ion trap 1 is disclosed comprising a segmented linear ion guide or ion trap. Ions are confined radially within the ion guide or ion trap 1 by the application of an AC or RF voltage to the electrodes. Ions are trapped within an axial quadratic potential well which is oscillated or modulated axially so as to cause ions to be ejected from the ion guide or ion trap 1 in a substantially non-resonant manner.

    摘要: An ion guide or ion trap is disclosed having an entrance electrode and an exit electrode. The potential of the exit electrode is periodically dropped for a relatively short period of time allowing some ions to escape from the ion guide or ion trap via an aperture in the exit electrode. The period of time that the potential of the exit electrode is dropped for is progressively increased and ions emerge from the ion guide or ion trap in a mass to charge ratio dependent manner. The ion guide or ion trap may be operated as a mass separator or low resolution mass analyser.
