摘要： A mass spectrometer is disclosed comprising a vortex mass filter/analyser. The vortex mass filter/analyser preferably comprises a chamber with a central rotatable shaft connected to a pressure reducing means. As the shaft rotates, a vortex is created within the chamber. The centrifugal force on an ion in the vortex is arranged to be balanced at a certain radius of rotation within the chamber by the electric force due to an opposed radial electric field. Ions having a certain mass to charge ratio are arranged to be maintained at a stable equilibrium at this radius and can then be selectively removed for further analysis. With this arrangement, no magnetic field is required and the apparatus can operate at pressures around that of atmospheric pressure.

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 comprising a FAIMS device comprising two parallel electrodes (9a, 9b) in series with an ion mobility separator (12) forming part of a mass spectrometer. Ions are separated in the FAIMS device (9a, 9b) according to their rate of change of ion mobility with electric field strength. The ions which are onwardly transmitted from the FAIMS device (9a, 9b) are then passed to an ion separator device (12) comprising a plurality of electrodes (12) and an optional ion trapping region (33). Ions are radially confined with the ion separator by application of an AC or RF voltage to the electrodes (12) and ions are separated according to their ion mobility by applying an axial DC voltage gradient which may remain constant as a function of time or which may vary with time.

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.
