摘要： A mass spectrometer 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 forming the ion guide or ion trap. A quadratic DC potential is applied along the axial length of the ion guide or ion trap in order to cause trapped ions to perform simple harmonic motion within the ion guide or ion trap. The frequency of the oscillations of the ions is detected using one or more inductive detectors. The mass to charge ratio of the ions can then be determined from the determined frequency of oscillations.

摘要： A mass spectrometer is disclosed wherein a z-lens upstream of an orthogonal acceleration Time of Flight mass analyser is repeatedly switched between a first mode wherein ions are transmitted to the mass analyser for subsequent mass analysis with a relatively high transmission and a second mode wherein ions are transmitted with a relatively low transmission. If it is determined that mass spectral data obtained when the mass analyser is in the first mode is suffering from saturation, then suitably scaled mass spectral data obtained when the mass analyser is in the second mode is used instead. If the saturation is severe then the mass spectral data obtained in the first mode may be replaced in its entirety with mass spectral data obtained in the second mode.

摘要： An ion detector for a mass spectrometer is provided wherein a mask (10) is provided between a first microchannel plate (2a) and a second microchannel plate (2b). The mask (10) prevents ion arrival events causing a cloud of secondary electrons to be from the second microchannel plate (2b) which would illuminate two collection anodes (5,6) at substantially the same time. The mask (10) also prevents electron clouds emitted which would otherwise vary significantly in intensity.

摘要： A mass spectrometer is disclosed wherein the experimentally determined mass to charge ratios of ions are reported together with an error band for each mass to charge ratio determination. The error band may, for example, reflect a 95% probability or confidence that the real, true, actual or accepted mass to charge ratio of the ion lies within the error band. By accurately determining the error band the possible candidate ions in a database can be accurately restricted whilst also guarding against over restriction.
