摘要： A mass spectrometer is disclosed wherein an ion beam attenuator is arranged upstream of an ion trap mass analyser. An ion tunnel ion trap comprising an upstream ion accumulation section and a downstream ion accumulation section is arranged upstream of the ion beam attenuator. Ions are released from the ion tunnel ion trap and the intensity of the ion beam which is transmitted to the ion trap analyser is controlled by the ion beam attenuator. The fill time during which ions are admitted into the ion trap mass analyser remains substantially constant and is substantially independent of the intensity of the ion beam.

摘要： A linear ion trap (6,7,8)is disclosed comprising a central quadrupole rod set (6)and a post-filter quadrupole rod set (8). A 180° phase difference is maintained between axially adjacent rod electrodes of the central quadrupole rod set (6) and the post-filter quadrupole (8) so that an axial pseudo-potential barrier is created between the central quadrupole rod set (6) and the post-filter quadrupole (8). A supplementary AC voltage is applied to the rods of the central quadrupole (6) in order to radially excite ions which are desired to be ejected from the ion trap. The ions are ejected from the ion trap (6,7,8) non-adiabatically in an axial direction.

摘要： A non-linear ion guide is disclosed comprising a plurality of electrodes. An ion guiding region is arranged between the electrodes, and the ion guiding region curves at least in a first direction. A DC voltage is applied to at least some of the electrodes in order to form a DC potential well which acts to confine ions within the ion guiding region in the first direction.

摘要： An ion guide or mass analyser is disclosed comprising a plurality of electrodes having apertures through which ions are transmitted in use. A pseudo-potential barrier is created at the exit of the ion guide or mass analyser. The amplitude or depth of the pseudo-potential barrier is inversely proportional to the mass to charge ratio of an ion. One or more transient DC voltages are applied to the electrodes of the ion guide or mass analyser in order to urge ions along the length of the ion guides or mass analyser. The amplitude of the transient DC voltage applied to the electrode may be increased with time so that ions are caused to be emitted from the ion guide or mass analyser in reverse order of their mass to charge ratio.

摘要： A mass spectrometer is disclosed comprising an ion trap and a fragmentation device. Ions are fragmented in the ion trap to form first generation fragment ions. The ion trap has a relatively high mass cut-off. The first generation fragment ions are then transferred to a fragmentation device which is arranged to have a substantially lower low mass cut-off. The first generation fragment ions are fragmented within the fragmentation device any may optionally be stored in an ion accumulation region prior to being passed to a mass analyser for subsequent mass analysis.

摘要： A Time of Flight mass analyser is disclosed wherein the time period between successive orthogonal acceleration pulses is less than the time of flight of ions having the maximum mass to charge ratio of interest. As a result, some ions are subject to wrap-around and will appear in a subsequent mass spectrum. Mass spectra obtained at two different sampling rates may be compared and mass peaks relating to ions which have and have not been subject to wrap-around may be identified.

摘要： A mass spectrometer is disclosed comprising an orthogonal acceleration Time of Flight mass analyser. A pulse or packet of ions is released either from an ion trap or alternatively from a travelling wave ion guide arranged upstream of an orthogonal acceleration electrode which forms part of the Time of Flight mass analyser.
