Abstract
Ion mobility spectrometers (IMS) are typically used for fast and sensitive detection of substances in the gas phase. IMS offer detection limits in the low pptv range with measurement times of less than one second. The measurement principle is based on the separation of different ion species according to their ion-specific mobility in a neutral drift gas under the influence of an electric field.
