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.

Trace vapor detection

To facilitate collection of sample, for analysis in an ion mobility spectrometer or the like, a collection device is provided which can be mounted on the fingers, for example two fingers, of a user's hand. The collection device is formed of top and bottom layers of a sheet material, which are secured together along three sides and open end along a fourth side, to enable the user's fingers to be inserted. Mounted on a user's fingers, the device is run over surfaces of interest to collect a sample. It is then placed in a frame holder, and then inserted into an inlet station of an analysis device. There, any substances of interest are caused to pass into the analysis device for a reading to be taken.
