The Collection and Detection of Accelerant Vapors Using Porous Polymers and Curie Point Pyrolysis Wires Coated with Active Carbon
The sampling of organic vapors from arson residues using different types of adsorbants is studied. Sampling tubes packed with porous polymers (Porapak Q and Tenax GC) as well as Curie point pyrolysis wires coated with finely divided or granular active carbon are used. The adsorption and desorption of several common accelerants carried out by these techniques is compared. The optimum conditions for applying the described techniques to the forensic science examination of fire debris are studied. Some comparisons with conventional headspace analysis of accelerant vapors are discussed.
