1. An ion transport device of a mass spectrometer, comprising:
a plurality of pole rod pairs arranged in parallel, the pole rod pairs defining a plurality of ion transport cells, each ion transport cell uniquely corresponding, to a contiguous group of a fixed number of pole rod pairs, such that no two ion transport cells share a common pole rod pair; a fragmentation cell for supplying ions to the ion transport device, wherein the ion transport device is positioned and oriented to receive ions from the fragmentation cell travelling in a direction parallel to the primary axes of the pole rods; and a controller configured to
apply voltages in a repeating pairs pattern to the pole rod airs thereby creating a plurality of potential wells capable of capturing ions, wherein each ion transport cell receives the same pattern of voltages;move the repeating voltage pattern along the pole rod pairs to move captured ions within and between the plurality of ion transport cells along the ion transport device; andapply at least one ejection voltage to one or more electrodes to cause ions to be ejected from the ion transport device in a direction parallel to the pole rods. |
