    摘要: An ion mobility spectrometer is disclosed wherein ions are passed through an ion mobility spectrometer (5) and become temporally separated. Ions having a relatively high ion mobility are transmitted by a non-destructive ion gate (6) but ions having a relatively low ion mobility are subsequently trapped within the ion mobility spectrometer (5) when the ion gate (6) is switched so as to prevent ions from being onwardly transmitted. Ions which are transmitted by the ion gate (6) are trapped in a downstream ion trap (7). The ions are then returned back upstream to a second upstream ion trap (4).

    摘要: An ion detector system for a mass spectrometer is disclosed comprising an ion detector comprising an array of detector elements. The ion detector system is arranged to correct for tilt and non-linear aberrations in an isochronous plane of ions. The ion detector system generates separate first mass spectral data sets for each detector element and then applies a calibration coefficient to each of the first mass spectral data sets to produce a plurality of second calibrated mass spectral data sets. The plurality of second calibrated mass spectral data sets are then combined to form a composite mass spectral data set.
