Monitoring of selected skin- and breath-borne volatile organic compounds emitted from the human body using gas chromatography ion mobility spectrometry (GC-IMS).

摘要: Abstract Human smuggling and associated cross-border crimes have evolved as a major challenge for the European Union in recent years. Of particular concern is increasing trend of migrants hidden inside shipping containers or trucks. Therefore, there growing demand portable security devices non-intrusive rapid monitoring to detect people hiding inside. In this context, chemical analysis volatiles organic compounds (VOCs) emitted from human body proposed locating tool. present study, an in-house made ion mobility spectrometer coupled with gas chromatography (GC-IMS) was used monitor volatile moieties released under conditions that mimic entrapment. A total 17 omnipresent were identified quantified 35 peaks corresponding presence. These are 7 aldehydes (acrolein, 2-methylpropanal, 3-methylbutanal, 2-ethacrolein, n-hexanal, n-heptanal, benzaldehyde), 3 ketones (acetone, 2-pentanone, 4-methyl-2-pentanone), 5 esters (ethyl formate, ethyl propionate, vinyl butyrate, butyl acetate, isovalerate), one alcohol (2-methyl-1-propanol) acid (acetic acid). The limits detection (0.05–7.2 ppb) relative standard deviations (0.6–11%) should be sufficient detecting these markers presence field conditions. This study shows GC-IMS can detector entrapped people.
