Abstract
The present invention relates to ion mobility spectrometers. In one embodiment, the ion mobility spectrometer of the present invention uses a simplified ion mobility spectrometer design having helical resistive material to form substantially constant electric fields that guide ion movements. The drift tube for ion mobility spectrometers described herein is constructed with a non-conductive structure. This configuration provides a robust ion mobility spectrometer that is simple to build. One feature of the present invention is that the drift tube design described herein enables the ion mobility spectrometer to be built with a lower weight, lower power consumption, lower manufacturing cost, and free of sealants.
