TRACE VAPOR DETECTION

摘要

A method and device for the detection of vapours of cocaine and associated compounds are disclosed. The method involves sampling a volume of air suspected of containing cocaine vapours, passing this air through a filtration system that removes any particulate matter and binds vapours of cocaine and associated compounds, if present, for further analysis. A preferred associated compound-vapour is that of ecgonidine methyl ester. 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.
