ABSTRACT:
A drift tube for an ion mobility spectrometer is assembled from stacked tube segments and has electrodes that generate an electric drift field and are electrically contactable from the outside of the drift tube. Most of the tube segments have at least two separate apertures so that, when the segments are stacked, these apertures form a drift region and at least one integrated gas channel both of which run parallel to the axis of the drift tube. At least one tube segment is inserted into the stack in which the two apertures are connected to form a gas channel transverse to the axis of the drift tube so that the drift region is connected to the gas channel at that tube segment.
