Abstract
One embodiment of the present disclosure provides an ion mobility spectrometry (IMS) device for performing chemical analysis. The IMS device includes a first set of electrodes arranged linearly in a first direction and separated by a first set of gaps. The IMS device includes a second set of electrodes positioned directly opposing the first set of electrodes to match the first set of electrodes on a one-to-one basis, wherein the second set of electrodes are separated by a second set of gaps. The IMS device includes a drift region between the first set of electrodes and the second set of electrodes, wherein charged particles enter at a first end of the drift region and traverse the drift region along the first direction. The IMS device additionally includes a detector positioned at a second end of the drift region and configured to receive charged particles exiting the drift region.
