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.
A method for the detection of cocaine, comprising obtaining a sample of air, passing the sample through a filter capable of retaining the vapors of cocaine and associated compounds, removing the compounds from the filter and detecting the presence of cocaine and associated compounds said associated compounds having a higher vapor pressure than that of cocaine, and said associated compounds containing the molecular bicyclic structure of cocaine.
A filter capable of binding vapors of ecgonidine methyl ester (EDME), chosen from the group consisting of tissue, cloth or mesh made from paper, cotton wool, metal, or TEFLON.RTM. and which has been treated with activating material which remains on the filter and enhances the binding of EDME.
A device for sampling air suspected of containing vapors of cocaine and associated compounds, comprising a nozzle made up of:
