Huang et al. [16] applied a second form of solvent extraction for arson debris using (SFE). The recoveries of various ignitable liquid residues from carpet were above 80% with a low degree of co-extraction of interfering compounds. Other traditionally used sample preparation techniques are steam and vacuum distillation, which have been applied to complex matrices. Steam distillation [17] is used for large amounts of ignitable liquids in samples and commonly, the extraction solvent is n-hexane, which provides high recovery efficiency. Vacuum distillation is useful in the case of fragile samples such as burned documents. Howev- er, the time of distillation and use of hazardous solvents outweigh the benefits [2]. In addition the pre-concentration of analytes on activated charcoal strips (ACS) [18,19] and Tenax GC [20,21] have been the most commonly used sorbents for evaluation, but may require the use of hazardous solvents and/or additional thermal desorption equipment.
