Application of air sampling and ion-mobility spectrometry to narcotics detection: a feasibility study.
A feasibility study of the application of air sampling and ion-mobility spectrometry (IMS) for detection of heroin and cocaine concealed in letter mail showed that a unique IMS signature is associated with each type of drug and that a number of IMS peaks can be used as markers for the presence of drugs. No false reading for cocaine or heroin resulted when innocent items were monitored. Near real-time performance with sampling and analysis times of less than 30 seconds was achieved for the simultaneous detection of cocaine and heroin. The method proved to be a reliable tool for the fast screening of suspect items. Preliminary tests also showed that the method has potential for use in detecting the drugs in suitcases and on people.
