Abstract
An ion transport device of a mass spectrometer includes a plurality of pole rod arranged in first and second parallel rows and a controller. The controller is configured to apply voltages in a repeating voltage pattern to the pole rods of the first row and apply a common voltage to the pole rods of the second row 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 rods of the first row to move captured ions within and between the plurality of ion transport cells along the ion transport device; and apply at least one ejection voltage to one or more electrodes to cause ions to be ejected from the ion transport device.
