“…Since the sensitivity of the canine nose is dependent upon the training it receives, inconsistent training from variations in available drug training aids between agencies, along with natural differences in sensitivity inherent to biological specimens, may result in the threshold variation [104,107]. In order to determine the field threshold levels of piperonal dogs trained to detect ecstasy, piperonal COMPS were prepared at several different orders of magnitude in permeation of the target odorant.…”

“…These odour mimics can allow for training to be performed with non-controlled materials instead of the actual illicit substances [31][32][33]. The need to possess actual illicit substances can be challenging for some trainers/organizations in order to adhere to various licensing and regulatory guidelines required to maintain possession of these controlled substances.…”

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.

“…A one-step absorption/derivatization SPME methodology was used for the analysis of amphetamine and MAMP from urine specimens. 68,69 3.43.5 Applications of SPME for Chemical Warfare Agents SPME applications for sampling and analysis of chemical warfare agents (CWAs) has gained attention in recent years for many forensic investigations of counterterrorism. Specifically for this study, S-(À)-N-(trifluoroacetyl)-prolyl chloride was used as the chiral derivatizing agent, which was added directly to the urine sample matrix.…”
