Abstract
A hybrid ion mobility spectrometer includes a single-pass drift tube having an ion inlet and an ion outlet, a multiple-pass drift tube having an ion inlet and an ion outlet each coupled to the single pass drift tube between the ion inlet and the ion outlet thereof, and at least one ion steering channel controllable to selectively pass ions traveling through the single-pass drift tube into the multiple-pass drift tube via the ion inlet of the multiple-pass drift tube and to selectively pass ions traveling through the multiple-pass drift tube into the single-pass drift tube via the ion outlet of the multiple-pass drift tube. The single-pass drift tube separates in time ions traveling therethrough according to a first function of ion mobility, and the multiple-pass drift tube separates in time ions traveling one or more times therethrough according to the first or a second function of ion mobility.
