The frequency of occurrence and discriminatory power of compounds found in human scent across a population determined by SPME-GC/MS

High throughput volatile fatty acid skin metabolite profiling by thermal desorption secondary electrospray ionisation mass spectrometry

“…Individual skin profiles have been developed as 'barcodes' of scent for forensic [21] and diagnostic application [22], and gender and age specific signatures have been proposed as contributing factors to an individual's profile [23][24][25][26]. Olfactory analysis, either in-vivo or by organoleptic analysis of chromatographic eluents [27], combined with analytical measurement have established levels of odour to correlate with VSCs and VFAs, with 3-methyl-2-hexenoic acid cited as a critical molecular factor [26][27][28].…”

The Development of an Optimized System of Narcotic and Explosive Contraband Mimics for Calibration and Training of Biological Detectors

“…In general, a gun is a combination of metal, plastic, and/or wood assembled into a decanal [90,110]), while the later portion of the chromatograms show characteristic profiles that are common to petroleum products. Since the firearms had been handled by the donating officers, and the officers had previously used cleaners and oils to maintain the firearms, these results were expected.…”

Resistance of human odours to extremely high temperature as revealed by trained dogs

“…For forensic purpose the hand odour is very interesting, because the perpetrator usually touches the object at the crime scene with hands (Curran et al 2007).…”

“…Skin is supposed to be a significant source of scent traces (Prada et al 2011). Human scent is a complex combination of volatile organic compounds (VOC) such as acids, alcohols, aldehydes, hydrocarbons, esters, and ketones that secret fluids onto the human skin where they interact with skin bacteria (Labows et al 1982;Stoddart 1999;Syrotuck 2000;Curran et al 2005Curran et al , 2007Curran et al , 2010a. Production of VOCs is managed mainly by the secretion of three types of glands: eccrine, sebaceous, and apocrine (Curran et al 2007).…”

Production of VOCs is managed mainly by the secretion of three types of glands: eccrine, sebaceous, and apocrine (Curran et al 2007). Using solid phase micro-extraction gas chromatography/mass spectrometry has shown that human scent consists of a great amount of compounds that differ qualitatively and quantitatively from person to person (Curran et al 2005;Penn et al 2007).…”
