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 optimize the fragmentation energy of ions as they enter the collision or fragmentation cell (5).

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.

摘要: A mass spectrometer includes an ion detector positioned upstream of a quadrupole mass filter/analyser. Ions are passed through the quadrupole mass filter/analyser, stored in an ion trap and then passed back through the same mass filter/analyser before being detected by the upstream ion detector. With this arrangement, MS/MS experiments can be performed using an apparatus having only a single mass filter/analyser.

摘要: A mass spectrometer comprising an ion mobility separator for separating ions according to their ion mobility is disclosed. The ion mobility separator comprises a plurality of electrodes and one or more transient DC voltages or one or more transient DC voltage waveforms are progressively applied to the electrodes so that ions having a certain ion mobility are separated from other ions having different ion mobilities.
