Abstract:
An ion mobility spectrometer instrument has a drift tube that is partitioned into a plurality of cascaded drift tube segments. A number of electric field sources may each be coupled to one or more of the plurality of drift tube segments. A control circuit is configured to control operation of the number of the electric field sources in a manner that sequentially applies electric fields to the drift tube segments with a magnitude of at least one being different than the others to allow only ions having a predefined ion mobility or range of ion mobilities to travel through the drift tube. Alternatively, the length of at least one of the drift tube segments may be made different from those of the others to produce the same result. The drift tube segments may define a linear drift tube or a closed drift tube with a continuous ion travel path.

Claim (Index 18):
The ion mobility spectrometer instrument of  claim 15 , wherein \u03a6=2 such that a first one of the two electric field activation sources, when activated, establishes a repulsive electric field in sequentially odd numbered ones of the plurality of ion elimination regions and an electric drift field in sequentially even numbered ones of the plurality of ion elimination regions and also in each of the plurality of cascaded drift tube segments, and a second one of the two electric field activation sources, when activated, establishes a repulsive electric field in sequentially even numbered ones of the plurality of ion elimination regions and an electric drift field in sequentially odd numbered ones of the plurality of ion elimination regions and also in each of the plurality of cascaded drift tube segments,\n and wherein the phase ratio, \u03b6, is the ratio of the magnitude of the electric drift field established by the first one of the electric field activation sources and the magnitude of the electric field established by the second one of the electric field activation sources.
