摘要： An ion mobility separator or spectrometer is disclosed comprising an inner cylinder (2) and an outer cylinder (1). The inner cylinder (2) and the outer cylinder (1) define an annular volume (3) through which ions are transmitted. One or more spiral electrodes a-f are arranged on a surface of the inner cylinder (2) and/or on a surface of the outer cylinder (1). A first device is arranged and adapted to maintain a DC electric field and/or a pseudo- potential force which acts to urge ions from a first end of the ion mobility separator or spectrometer to a second end of the ion mobility separator or spectrometer. A second device is arranged and adapted to apply one or more transient DC voltages to the one or more spiral electrodes in order to urge ions towards the first end of the ion mobility separator or spectrometer. The net effect is to extend the effective path length of the ion mobility separator.

摘要： A method of mass spectrometry is disclosed comprising providing a flight region for ions to travel through and a detector or fragmentation device. A potential profile is maintained along the flight region such that ions travel towards the detector or fragmentation device. The potential at which a first length of the flight region is maintained is then changed from a first potential to a second potential whilst at least some ions are travelling within the first length of flight region. The changed potential provides a first potential difference at an exit of the length of flight region, through which the ions are accelerated as they leave the length of flight region. This increases the kinetic energy of the ions prior to them reaching the detector or fragmentation cell.

摘要： A Time of Flight mass analyser is disclosed comprising an annular ion guide having a longitudinal axis and comprising a first annular ion guide section and a second annular ion guide section. Ions are introduced into the first annular ion guide section so that the ions form substantially stable circular orbits within the first annular ion guide section about the longitudinal axis. An ion detector is disposed within the annular ion guide. Ions are orthogonally accelerated in a first axial direction from the first annular ion guide section into the second annular ion guide section. An axial DC potential is maintained along at least a portion of the second annular ion guide section so that the ions are reflected in a second axial direction which is substantially opposed to the first axial direction. The ions undergo multiple axial passes through the second annular ion guide section before being detected by the ion detector.
