Abstract
The invention relates to a method and an ion mobility spectrometer (IMS) for the detection of contaminations by explosives, drugs, wood preservatives or the like. The substance traces collected on a carrier material, e.g. cellulose, are dissolved in a solvent for detection using an IMS and are vaporized together with this solvent from a sample dispenser in the reaction compartment of the IMS. In this way, the sample dispenser can be operated at a considerably lower temperature.
