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.

摘要： An ion detector for a mass spectrometer is disclosed comprising a microchannel plate 8 which receives ions 12 at an input surface and releases electrons 16 from an output surface. A detecting device is arranged to receive at least some of the electrons 16 emitted from the microchannel plate 8. The detecting device receives electrons 16 on a first portion of the detecting device at a first time t1 and receives electrons 16 on a second different portion of the detector at a second later time t2. Time-varying electric and/or magnetic fields are applied between the microchannel plate 8 and the detecting device to guide electrons 16 emitted from the microchannel plate onto different regions of the detecting device in a time varying manner.

摘要： A mass spectrometer is disclosed comprising a Time of Flight mass analyzer comprising an ion detector comprising an Analog to Digital Converter. Signals from the Analog to Digital Converter are digitized and the arrival time and intensity of ions are determined. The arrival time T0 and intensity S0 of each ion arrival event is converted into two separate intensities S(n),S(n+i) which are stored in neighboring time bins T(n), T(n+1).

摘要： A mass spectrometer is disclosed comprising a 2D or 3D ion trap. The 2D ion trap comprises a quadrupole rod set ion trap wherein a slot is provided in each of the rods to allow ions to be ejected radially from the ion trap. The 3D ion trap comprises a central ring electrode which is radially segmented and wherein a slot is provided in each radial segment to allow ions to be ejected radially from the ion trap. Ions having different mass to charge ratios and/or opposite polarities may be simultaneously ejected from the ion trap via different exit pathways.

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： 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 Time of Flight mass analyser is disclosed comprising an ion detector comprising an Analogue to Digital Converter. Output signals from the ion detector are digitised and the arrival times and intensity values relating to ion arrival events are determined. If the determined arrival times from two signals fall within the same time window then the arrival times are added together in a weighted manner and the intensity values are combined.

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.
