Abstract
An improved method of extraction, detection, and characterization of a vapor from an explosive, a taggant in an explosive, a controlled substance, a biohazard, and mixtures thereof uses a new and improved SPME device for extraction and ion mobility spectrometry for detection and characterization. The new and improved SPME device has an increased capacity to sorb a target vapor. The increased sorption of vapor provides for more accurate detection by an ion mobility spectrometer. A SPME device having increased surface area may be exposed to an atmosphere in an enclosure containing a test object or a volume of gas that was in contact with the test object to allow for sorption of the target vapor and then introduced into an IMS for more accurate detection and characterization of the vapor due to the increased sorption of the vapor by the SPME device described herein.
