Abstract
A carrier for contraband substances to be used as a reference for testing trace detection systems. The carrier, which has the consistency of hand cream and can be dispensed from a tube or a syringe, is inert with respect to the contraband substances and does not dissolve or degrade the plastics normally used for making luggage or computer disc cases. After the carrier (with added contraband substance) has been placed on a hard surface such as a plastic luggage handle and dried, the contraband substance can be sampled by wiping with a paper or cloth, which is then tested in a device that uses ion mobility spectrometry, gas chromatography, chemiluminescence, or a combination of these methods.
