ABSTRACT:
Apparatus is described for securing vapor samples, particularly from articles such as suitcases, travel bags, packages, and the like. The apparatus may include several depressor arms hinged above a station along a conveyor belt or the like. A sampling probe for sampling vapor expelled from the articles is positioned at the station. As the articles are carried by the conveyor past the station, they lift the arms which are suitably hinged above them so that the weight of the arms causes a part of the vapor accumulated in the article to be expelled. The expelled vapor is sampled by the probe at the station and may be carried to a suitable vapor analyzer for test.
