Abstract
An ion mobility spectrometer wherein ions are separated along a drift axis while providing a drift gas flow in a direction that is substantially neither in the direction of the drift axis nor opposite to the drift axis. An ion mobility spectrometer and operation methods use a cross-directional gas flow in a drift tube and/or a segmented drift tube for pre-separation.
