    摘要: A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator (3) arranged upstream of a collision or fragmentation cell (5). Ions are separated according to their ion mobility within the ion mobility spectrometer or separator (3). The kinetic energy of the ions exiting the ion mobility spectrometer or separator (3) is increased substantially linearly with time in order to optimise the fragmentation energy of ions as they enter the collision or fragmentation cell (5).

    摘要: A mass spectrometer is disclosed comprising an ion mobility spectrometer or separator (6) arranged upstream of a collision or fragmentation cell (8). Ions are separated according to their ion mobility within the ion mobility spectrometer or separator (6). The kinetic energy of the ions exiting the ion mobility spectrometer or separator (6) is increased substantially linearly with time in order to optimise the fragmentation energy of ions as they enter the collision or fragmentation cell (8). During the time that the potential of the ion mobility spectrometer or separator (6) is being varied, the potential of ion-optical components upstream of the ion mobility spectrometer or separator (6) such as an ion source (1), ion guide (2), quadrupole mass filter (3), optional second collision or fragmentation cell (4) and an ion trapping device (5) are kept constant.

    摘要: A mass spectrometer is disclosed comprising an ion mobility spectrometer (8) and an ion gate (9). A collision cell (10) is arranged downstream of the ion gate (9). The operation of the ion mobility spectrometer (8) and the ion gate (9) are synchronised so that only ions having a particular mass to charge ratio and a desired charge state are onwardly transmitted to the collision cell (10).

    摘要: A closed-loop ion guide (1) is disclosed comprising a plurality of electrodes having apertures through which ions are transmitted in use. Ions are injected into the closed-loop ion guide (1) and may make several circuits of the closed-loop ion guide (1) before being ejected from the ion guide (1). In a mode of operation the ion guide (1) may be arranged to separate ions temporally according to their ion mobility.
