ABSTRACT:
Device for carrying out a method of odor detection comprising, in particular, a plurality of chambers, each including a plurality of semiconductor gas sensors, conductive polymer gas sensors, and surface acoustic wave gas sensors, as detection devices, a variable flow gas pump for forming a gas flow in said chambers, measurement electronic device for operating the detection devices, a data processing unit for recording in a file the olfactory prints obtained using the detection means, and for comparing the detected impressions with those in the file so that odors may be identified and recognized. Applications exist, especially to drugs, explosives, body odors and food seals.
