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.

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 (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： 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.

An ion guiding region is arranged between the electrodes, and the ion guiding region curves at least in a first direction.

A control system applies a first extraction pulse to an acceleration electrode in order to accelerate a first group of ions into the time of flight region at a first time T1, wherein ions having the lowest mass to charge ratio in the first group of ions have a time of flight ΔT1min through the time of flight region and ions having the highest mass to charge ratio in the first group of ions have a time of flight ΔT1max through the time of flight region. The control system applies a second extraction pulse to the acceleration electrode at a subsequent second time T2, wherein ΔT1max−ΔT1min≦T2−T1
