摘要： An ion guide is disclosed comprising a plurality of electrodes. A first device is arranged and adapted to apply a RF voltage to at least some of the electrodes in order to form, in use, a pseudo-potential well which acts to confine ions in a first direction within the ion guide. A second device is arranged and adapted to apply a DC voltage to at least some of the electrodes in order to form, in use, a DC potential well which acts to confine ions in a second direction within the ion guide. A third device is arranged and adapted to cause ions having desired or undesired mass to charge ratios to be mass to charge ratio selectively ejected from the ion guide in the second direction.

摘要： An ion guiding device is disclosed comprising a first ion guide which is conjoined with a second ion guide. Ions are urged across a radial pseudo-potential barrier which separates the two guiding regions by a DC potential gradient. Ions may be transferred from an ion guide which has a relatively large cross-sectional profile to an ion guide which has a relatively small cross-sectional profile in order to improve the subsequent ion confinement of the ions.

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 a first chamber (10) and a second chamber (5). The second chamber (5) is located downstream of the first chamber 10 and an inter-chamber aperture (12) is provided between the two chambers (5,10). An ion guide (13) is located in the first chamber (10) and an ion mobility spectrometer (6) is located in the second chamber (5). Helium gas is provided to the first chamber (10). As ions are accelerated towards the ion mobility spectrometer 6 from a relatively low pressure region they pass initially into the first chamber (10). The helium gas provided in the first chamber (10) minimises ion fragmentation and ion discrimination effects as ions are accelerated into a relatively high pressure region. The ions are then transmitted by the ion guide (13) and are subsequently transmitted to the ion mobility spectrometer (6) located in the second chamber (5).

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.
