摘要： An ion guide is disclosed wherein an axial DC voltage barrier is created at the exit of the ion guide. A primary RF voltage is applied to the electrodes in order to confine ions radially within the ion guide. A supplemental RF voltage is also applied to the electrodes. The supplemental RF voltage has a greater axial repeat length than that of the primary RF voltage. The amplitude of the supplemental RF voltage is increased with time causing ions to become unstable and gain sufficient axial kinetic energy such that the ions overcome the axial DC voltage barrier. Ions emerge axially from the ion guide in mass to charge ratio order.

摘要： A mass spectrometer is disclosed comprising a quadrupole rod set ion trap (2, 3) wherein a potential field is created at the exit of the ion trap (4, 5) which decreases with increasing radius in one radial direction. Ions within the ion trap (2, 3) are mass selectively excited in a radial direction. Ions which have been excited in the radial direction experience a potential field which no longer confines the ions axially within the ion trap but which instead acts to extract the ions and hence causes the ions to be ejected axially from the ion trap (2, 3).

摘要： An ion guide or mass analyser (2) is disclosed comprising a plurality of electrodes (2a) 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 (2). 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 (4) are applied to the electrodes (2a) of the ion guide or mass analyser (2) in order to urge ions along the length of the ion guides or mass analyser (2). The amplitude of the transient DC voltage (4) applied to the electrode (2a) may be increased with time so that ions are caused to be emitted from the ion guide or mass analyser (2) in reverse order of their mass to charge ratio.

摘要： A mass filter is disclosed comprising an orthogonal acceleration electrode 9. Ions entering the mass filter are orthogonally accelerated by the orthogonal acceleration electrode 9 in a primary acceleration region 2 and enter a flight region 3. The ions 6,7,8 are then reflected by a reflectron 4 and are directed towards an exit region of the mass filter. Ions having a desired mass to charge ratio are arranged to arrive in the primary acceleration region 2 at a time when a voltage pulse applied to the orthogonal acceleration electrode 9 falls from a maximum to zero. Ions having a desired mass to charge ratio are orthogonally decelerated such that they have a zero component of velocity in the orthogonal direction. Accordingly, ions having a desired mass to charge ratio exit the mass filter in an axial direction.
