摘要： An ion guide or ion trap (1) is disclosed having an entrance electrode (2) and an exit electrode (3). The potential of the exit electrode (3) is periodically dropped for a relatively short period of time allowing some ions to escape from the ion guide or ion trap (1) via an aperture in the exit electrode (3). The period of time that the potential of the exit electrode (3) is dropped for is progressively increased and ions emerge from the ion guide or ion trap (1) in a mass to charge ratio dependent manner. The ion guide or ion trap (1) may be operated as a mass separator or low resolution mass analyser.

摘要： A mass spectrometer is disclosed comprising a quadrupole rod set ion guide or mass filter device. Broadband frequency-signals (13, 14, 15) having a plurality of frequency notches (16a; 16b; 16c) are applied sequentially to the rods of the quadrupole rod set. The notched broadband frequency signals (16a, 16b, 16c) cause undesired ions to be resonantly or parametrically ejected from the ion guide. The resulting ion signals are deconvoluted to provide a mass spectrum.

摘要： A mass spectrometer is disclosed comprising a time of flight mass analyser (7). The time of flight mass analyser (7) comprises an ion guide comprising a plurality of electrodes (1) which are interconnected by a series of resistors (2) forming a potential divider. Ions are confined radially within the ion guide by the application of a two-phase RF voltage to the electrodes (1). A single phase additional RF voltage is applied across the potential divider so that an inhomogeneous pseudo-potential force is maintained along the length of the ion guide.

摘要： A Time of Flight mass analyser is disclosed wherein the time period between successive orthogonal acceleration pulses is less than the time of flight of ions having the maximum mass to charge ratio of interest. As a result, some ions are subject to wrap-around and will appear in a subsequent mass spectrum. Mass spectra obtained at two different sampling rates may be compared and mass peaks relating to ions which have and have not been subject to wrap-around may be identified.

摘要： A mass spectrometer is disclosed comprising a quadrupole rod set ion guide or mass filter device (6). A broadband frequency signal (10) having one or more notches (11a, 11b, 11c) is applied to the rods of the quadrupole rod set (6). The notched broadband frequency signal (10) causes undesired ions to be resonantly ejected from the ion guide (6). The notched broadband frequency signal (10) has frequency components missing which correspond with the resonance frequency of ions which are desired to be onwardly transmitted. The ion guide or mass filter device (6) enables a plurality of desired ions having different mass to charge ratios to be simultaneously transmitted by the ion guide or mass filter device (6) whilst other ions are resonantly ejected from the ion guide or mass filter device (6).

摘要： A mass spectrometer is disclosed wherein an ion signal is split into a first and second signal. The first and second signals are multiplied by different gains and are digitised. Arrival time and intensity pairs are calculated for both digitised signals and the resulting time and intensity pairs are combined to form a high dynamic range spectrum. The spectrum is then combined with other corresponding spectra to form a summed spectrum.
