“…Twenty-one different explosive materials evaluated revealed that there were three common VOCs: DNT, trinitroglycerine (NG) and 2-ethyl-1-hexanol (2E1H), with DNT being the common odourant in all the explosives sampled ( figure 6). Similar analysis of a wide variety of explosive types resulted in the development of a six-member prototype training aid kit consisting of COMPS for 'plasticized, TNT-based, nitroglycerine-based, and tagged explosives, as well as for smokeless powders' [40,41]. This kit differed from others in that the substances used for the COMPS were safe to handle and could reduce the number of odours an explosive detection canine needed to be trained on.…”

This paper explores the advances made in identifying trace amounts of volatile organic compounds (VOCs) that originate from forensic specimens, such as drugs, explosives, live human scent and the scent of death, as well as the probative value for detecting such odours. The ability to locate and identify the VOCs liberated from or left by forensic substances is of increasing importance to criminal investigations as it can indicate the presence of contraband and/or associate an individual to a particular location or object. Although instruments have improved significantly in recent decades—with sensitivities now rivalling that of biological detectors—it is widely recognized that canines are generally still more superior for the detection of odourants due to their speed, versatility, ruggedness and discriminating power. Through advancements in the detection of VOCs, as well as increased standardization efforts for instruments and canines, the reliability of odour as evidence has continuously improved and is likely to continue to do so. Moreover, several legal cases in which this novel form of evidence has been accepted into US courts of law are discussed. As the development and implementation of best practice guidelines for canines and instruments increase, their reliability in detecting VOCs of interest should continue to improve, expanding the use of odour as an acceptable form of forensic evidence.

“…We have previously published data demonstrating the effect of sample volume on the concentration of volatile compounds in this container [1]. The key issue is determining how much 2E1H is required to saturate the headspace inside the sniffer tin, quart can and gallon can.…”
