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 6):
The ion mobility spectrometer instrument of  claim 1 , wherein the ion outlet of a last one of the drift tube segments is coupled by a last ion elimination region to the ion inlet of a first one of the drift tube segments such that the drift tube defines therein a closed and continuous ion travel path, the ion mobility spectrometer further comprising:\n an ion entrance drift tube segment having an ion inlet coupled to the ion source and an ion outlet coupled to the one of the plurality of cascaded drift tube segments, an ion exit drift tube segment having an ion inlet coupled to the one or another one of the plurality of drift tube segments, and an ion outlet, and an ion gate arrangement responsive to a first set of one or more ion gate signals to direct ions moving through the drift tube through the one or another one of the plurality of cascaded drift tube segments while blocking the ions from entering the ion exit drift tube segment, and to a second set of one or more ion gate signals to direct the ions moving through the drift tube into the ion exit drift tube segment while blocking the ions from moving through the one or another one of the plurality of cascaded drift tube segments, wherein the control circuit to produce the first set of one or more ion gate signals to cause only ions supplied by the ion source that have the predefined ion mobility or range of ion mobilities to travel through the drift tube, and after the ions have traveled around the drift tube a selected number of times to produce the second set of one or more ion gate signals to draw ions moving through the drift tube out of the drift tube and into the ion exit drift tube segment where the ions exit via the ion mobility spectrometer via the ion outlet of the ion exit drift tube segment.
