Arsonists may use a variety of possible accelerants to set a fire. During the examination of a potential arson scene, cause and origin investigators collect fire debris that they believe contains residues of these accelerants. The debris is placed in airtight containers to avoid possible loss of the volatile components and is transported to the laboratory for analysis. Utilizing a Gas Chromatography-Mass Spectrometry, traces of ignitable liquid residue can be identified in these samples. Often, the samples will have to concentrated for small amounts of residue. They accomplish this by adsorbing the accelerant residue onto activated charcoal strips. The concentrated accelerant is then eluted off the strip by dissolving in a solvent. Activated charcoal strips are used to maximize the containment of accelerants at fire scenes. The introduction of commercially produced activated charcoal strips into fire debris analysis has provided an easy, efficient and cost effective method for accelerant extraction. This method provides a simple, clean and sensitive method of accelerant extraction.
