    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: A mass spectrometer is disclosed comprising a mass selective ion trap or mass analyser (4) arranged upstream of an ion guide (6). Ions are scanned out of the mass selective ion trap or mass analyser (4) and are received in one or more axial potential wells created or formed within the ion guide (6). One or more transient DC voltages or potentials are preferably applied to the ion guide (6) in order to create a plurality of axial potential wells which are translated along the length of the ion guide (6). Ions are released in packets from the exit of the ion guide (6) and are orthogonally accelerated into a drift or flight region of an orthogonal acceleration Time of Flight mass analyser (13) with a relatively high duty cycle.

    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 (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.
