Abstract
A mass analyzer having a set of rods, e.g. quadrupole rods, into which ions are injected axially and are then contained by the combination of collision gas in the volume between the rods and end lenses which prevent the ions from leaving the volume between the rods. After the ions have been contained and manipulated, they are ejected radially through an opening or slot in one of the rods for detection. The configuration provides many of the advantages of a conventional ion trap, e.g. greater sensitivity, while avoiding a number of disadvantages of a conventional trap. If desired ions can be dissociated by applying an axial oscillating field, before being radially ejected.
