  • Trace vapor detection
    Patent number: 5859362
    Abstract: A method and device for the detection of vapors of cocaine and associated compounds are disclosed. The method involves sampling a volume of air suspected of containing cocaine vapors, passing this air through a filtration system that removes any particulate matter and binds vapors of cocaine and associated compounds, if present, for further analysis. A preferred associated compound-vapor is that of ecgonidine methyl ester (EDME), and a marker for the presence of cocaine. The device is comprised of a sampling, filtration and vacuum port components and can be easily attached to a container, and suction source, for the sampling of air.
