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 15):
An ion mobility spectrometer instrument, comprising:\n a drift tube partitioned into a plurality of cascaded drift tube segments and ion elimination regions, each of the plurality of drift tube segments defining an ion inlet at one end, an ion outlet at an opposite end and a first distance between the ion inlet and the ion outlet, each of the plurality of ion elimination regions defining a second distance between the ion outlet of a different one of the plurality of drift tube segments and the ion inlet of the next adjacent drift tube segment of the plurality of cascaded drift tube segments, an ion source coupled to one of the plurality of cascaded drift tube segments, one of an ion detector and an ion inlet of at least another ion mobility spectrometer instrument arranged to receive ions exiting the drift tube, an integer number, \u03a6, of electric field activation sources each operatively connected to one or more of the plurality of drift tube segments such that, when activated, each establishes a repulsive electric field in a different one of the first \u03a6 ion elimination regions and in every following \u03a6th ion elimination region, and also establishes an electric drift field in all remaining ion elimination regions and in all of the plurality of cascaded drift tube segments, and a control circuit to sequentially activate a number of times each of the integer number, \u03a6, of electric field activation sources for an activation duration while deactivating the remaining integer number, \u03a6, of electric field activation sources to thereby cause only ions generated by the ion source that have a predefined ion mobility or range of ion mobilities to traverse the drift tube, a ratio of a magnitude of the electric drift field established by one of the M electric field activation sources and the magnitude of the electric field established by at least one of the remaining electric field activation sources defining a phase ratio, \u03b6, the control circuit to control the magnitudes of the electric drift fields established by each of the integer number, \u03a6, of electric field activation sources such that \u03b6>0 and \u03b6\u22601.
