Detection of gasoline on suspects’ hands: Study of different sampling alternatives

Abstract

Highlights • ACC is suitable for the extraction and concentration of ignitable liquid residues • The sampling ability of ACS and ACC are comparable • The distance between the skin and the sorbent strongly influences the collection • The space between the hand and the glove or bag impacts the sampling of gasoline

“…Buchler et al examined five different collection methods with activated carbon cloth (ACC) and activated charcoal strips (ACS) for sampling ignitable liquids on hands [ 15 ]. ACC was shown to be as effective as ACS at recovering gasoline; however, distance between the adsorption material and skin and available headspace during sample collection were two key factors in extraction efficiency for both ACC and ACS.…”
