ION MOBILITY SPECTROMETER INSTRUMENT AND METHOD OF OPERATION |
摘要 |
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 activation 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 electric field activation sources in a manner that sequentially applies electric fields to the drift tube segments to allow only ions having a predefined ion mobility or range of ion mobilities to travel through the drift tube. The drift tube segments may define a linear drift tube or a closed drift tube with a continuous ion travel path. Techniques are disclosed for operating the ion mobility spectrometer to produce highly resolved ion mobility spectra.
