Abstract
A capillary microextractor of volatiles (CMV) allows the sampling of diagnostic volatiles that can be an explosive, explosive taggant, drug, poison, decomposition products thereof, a mixture of chemicals comprising an odor signature determined from detector dog trials, or volatile organic compounds indicative of a disease or other medical condition. The CMV has a thermally stable housing with orifices to allow the contact of a gas that contains one or more diagnostic volatiles with an absorbent that extracts and concentrates the diagnostic volatiles. After sampling, the CMV with the absorbed diagnostic volatiles can be placed in an ionized gas beam and introduced into a mass spectrometer or placed in a thermal desorption unit (TDU), where, upon heating, the diagnostic volatiles are released to an inlet port of an analytical instrument. Analytical instruments that can be used include gas chromatographs and ion mobility spectrometers for separation and mass spectrometers for unambiguous identification of the diagnostic volatiles.
