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. A static potential well is maintained along at least a portion of the axial length of the ion guide or ion trap (1). A time varying homogeneous electric field is applied along at least a portion of the axial length of the ion guide or ion trap (1). The combination of the static axial potential well and the time varying axial homogeneous electric field causes ions to be ejected from the ion guide or ion trap (1) in a substantially non-resonant manner.

摘要: A closed-loop ion guide 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 and may make several circuits of the closed-loop ion guide before being ejected from the ion guide. In a mode of operation the ion guide may be arranged to separate ions temporally according to their ion mobility.

摘要: A mass or mass to charge ratio selective ion trap is disclosed which directs ions into a small ejection region. A RF voltage acts to confine ions in a first (y) direction within the ion trap. A DC or RF voltage acts to confine ions in a second (x) direction. A quadratic DC potential well acts to confine ions in a third (z) direction within the ion trap. The profile of the quadratic DC potential well progressively varies along the second (x) direction.

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 analyzer.
