摘要： An ion guide or ion trap 1 is disclosed comprising a segmented linear ion guide or ion trap. Ions are confined radially within the ion guide or ion trap 1 by the application of an AC or RF voltage to the electrodes. Ions are trapped within an axial quadratic potential well which is oscillated or modulated axially so as to cause ions to be ejected from the ion guide or ion trap 1 in a substantially non-resonant manner.

摘要： A mass spectrometer is disclosed comprising an Electron Transfer Dissociation cell. Positive analyte ions are fragmented into fragment ions upon colliding with singly charged negative reagent ions with the cell. The cell comprises a plurality of ring electrodes which form a spherical trapping volume. Ions experience negligible RF heating over the majority of the trapping volume which enables the kinetic energy of the analyte and reagent ions to be reduced to just above thermal temperatures. An Electron Transfer Dissociation cell having an enhanced sensitivity is thereby provided. Fragment ions created within the cell may be cooled and may be transmitted onwardly to an orthogonal acceleration Time of Flight mass analyser enabling a significant improvement in the resolution of the mass analyser to be obtained.

摘要： A mass spectrometer is disclosed comprising a time of flight mass analyzer. The time of flight mass analyszr comprises an ion guide comprising a plurality of electrodes which are interconnected by a series of resistors forming a potential divider. Ions are confined radially within the ion guide by the application of a two-phase RF voltage to the electrodes. 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 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.

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

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 1 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 comprising an ion beam attenuator which attenuates an ion beam repeatedly switching between a zero transmission mode of operation during a time period ΔT1 and a non-zero transmission mode of operation during a time period ΔT2. The degree of attenuation of the ion beam can be varied by varying the mark space ratio ΔT2/ΔT1. The ion beam attenuator may release ions in packets or pulses but the packets or pulses of ions may be converted into a continuous ion beam by a relatively high pressure ion guide or gas collision cell arranged downstream of the ion beam attenuator.
