Abstract
In an ion mobility spectrometer, especially a miniaturized ion mobility spectrometer, the potential-conducting surfaces of the ion collector and ion gate form an angle less than 90° with the drift chamber axis. This makes it possible to provide openings in the face of the drift chamber for the required purge gas supply without limiting the size of the potential-conducting surface.
