    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: A mass spectrometer is disclosed comprising a device (2) which is operable in a first mode of operation to separate ions temporally according to their ion mobility by applying a continuous axial electric field. The device (2) is also operable in a second mode of operation wherein ions are separated temporally according to the their mass to charge ratio by pulsing an applied axial electric field ON and OFF.

    摘要: A mass spectrometer is disclosed comprising a first ion trap or ion guide (2), a single ion mobility spectrometer or separator stage (3) and a second ion trap or ion guide (4) arranged downstream of the ion mobility spectrometer or separator (3). In a mode of operation ions from the second ion trap or ion guide (4) are passed from the second ion trap or ion guide back upstream to the ion mobility spectrometer or separator (3).

    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 analyzer.
