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.desorption equipment.
