Abstract
Ion mobility spectrometry systems, devices, and associated methods of operation are disclosed herein. In one embodiment, a method for performing ion mobility spectrometry includes ionizing a sample in gas phase and applying an electric field to the ionized sample in the gas phase, thereby moving the ionized sample along a drift region. The applied electric field has a plurality of strength values with respect to time, and the individual strength values being generally constant during a corresponding period of time. The method further includes detecting an ion intensity and a drift time of the ionized sample moving through the drift region under the applied electric field with the plurality of strength values.
