Abstract
The invention relates to a gating element for switching or modulating the ion current in ion mobility spectrometers, particularly in miniature ion mobility spectrometers (IMS) operated at atmospheric pressure, where the ion current of an ion source is modulated with a continuous modulation function and the mobility spectrum is generated from the measured ion current by a correlation analysis with the modulation pattern. The invention proposes using a layered plate with apertures (apertured plate) rather than a grid (or a series of grids), said apertured plate comprising at least three conductive and two insulating (or low-conductivity) layers arranged alternately, which are firmly bonded with each other.
