Abstract

An ion mobility spectrometer having an ion source for generating ions; an ion detector for recording ions, and a number of substantially flat diaphragm electrodes arranged substantially perpendicular to a straight system axis that passes through the apertures in said diaphragms, with the diaphragms being arranged in a series of cells with each cell including an entrances and an exit diaphragm and a short region in between. The exit diaphragm of one cell is identical to the entrance diaphragm of the next cell, and the cells of said ion mobility spectrometer are grouped into three parts: an ion-beam forming region, an ion analyzing region, and a decelerating ion gate.
