摘要： An ion guide or ion trap is disclosed comprising a segmented linear ion guide or ion trap. Ions are confined radially within the ion guide or ion trap 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. A time varying homogeneous electric field is applied along at least a portion of the axial length of the ion guide or ion trap. 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 in a substantially non-resonant manner.

摘要： A mass spectrometer is disclosed comprising a mass filter for separating ions according to their mass to charge ratio. The mass filter comprises a plurality of electrodes wherein ions are radially confined within the mass filter by the application of AC or RF voltages to the electrodes. 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 mass to charge ratio are separated from other ions having different mass to charge ratios which remain radially confined within the mass filter.

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： A mass or mass to charge ratio selective ion trap is disclosed having an increased charge storage capacity. A RF voltage acts to confine ions in a first (y) direction within the ion trap. A DC voltage and/or an RF voltage acts to confine ions in a second (x) direction within the ion trap. A quadratic DC potential well acts to confine ions in a third (z) direction within the ion trap. Ions are excited in the third (z) direction and are caused to be mass or mass to charge ratio selectively ejected in the third (z) direction.

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.
