    摘要： There is disclosed a method of selectively extracting ions comprising the steps of: providing a supply of ions in a body of gas; generating a ponderomotive ion trapping potential generally along an axis; generating further potentials to provide an effective potential which prevents ions from being extracted from an extraction region; trapping ions in said effective potential; and selectively extracting ions of a predetermined m/z ratio or ion mobility from the extraction region; in which the characteristics of the effective potential which prevent ions from being extracted from the extraction region are caused, at least in part, by the generation of the ponderomotive ion trapping potential.

    摘要： A mass spectrometer is disclosed comprising an ion trap wherein ions which have been temporally separated according to their mass to charge ratio or ion mobility enter the ion trap. Once at least some of the ions have entered the ion trap, a plurality of ion trapping regions are created along the length of the ion trap in order to fractionate the ions. Alternatively, the ions may be received within one or more axial trapping regions which are translated along the ion trap with a velocity which is progressively reduced to zero.

    摘要： A method of mass spectrometry is disclosed wherein ions are trapped for a period of time T within an AC or RF ion guide maintained at a pressure P wherein the product P×T is at least 1 mbar-ms. The effect of trapping the ions according to a preferred embodiment is that singly charged ions which may, for example, comprise unwanted background ions are substantially lost from the trap whereas multiply charged analyte ions are maintained within the ion trap and can then be released for subsequent mass analysis.

    摘要： A mass spectrometer is disclosed wherein ions having a particular desired charge state are selected by operating an ion mobility spectrometer in combination with a quadrupole mass filter. Precursor ions are fragmented or reacted to form product ions in a collision cell ion trap and sent back upstream to an upstream ion trap. The fragment or product ions are then passed through the ion mobility spectrometer wherein they become temporally separated according to their ion mobility. Fragment or product ions are then re-trapped in the collision cell ion trap before being released therefrom in packets. A pusher electrode of a time of flight mass analyser is energised a predetermined period of time after a packet of ions is released from the collision cell ion trap. Accordingly, it is possible to select multiply charged precursor ions from a background of singly charged ions, fragment them, and mass analyse the fragment ions with a near 100% duty cycle across the whole mass range.
