    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: An ion trap mass analyser (1) is disclosed comprising a segmented rod set. Ions are trapped radially within the mass analyser by a radial pseudo-potential well. The ions are also confined axially within a quadratic axial potential well. A supplemental AC voltage or potential is applied to the electrodes comprising the ion trap mass analyser (1) in order to excite parametrically ions within the ion trap (1).

    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.
