Of recent, forensic toxicology laboratories have been grappling with the emergence of tetrahydrocannabinol isomers within biological specimens. Traditional methodologies are often inadequate in the separation of Δ9-tetrahydrocannabinol and Δ8-tetrahydrocannabinol, which are the most common isomers identified in forensic testing. This webinar focuses on the validation of a quantitative liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the analysis of tetrahydrocannabinol isomers in biological matrices and the analytical challenges associated with these compounds.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on June 25, 2024.

This webinar discusses the essential aspects of best practice using liquid chromatography diode array detector (LC-DAD) with optional electrospray ionization mass spectrometry (ESI/MS) for compliance testing of hemp and hemp-derived products. The key topics of this webinar will include: 1) an overview of the most effective LC separation published so far; 2) a description of a simple methanol extraction procedure, consisting of homogenization, ultrasonication/pulverization, centrifugation, filtration, and dilution, to recover cannabinoids from a wide range of samples; 3) how to utilize ultraviolet (UV) detection at multiple wavelengths for optimal sensitivity and improved selectivity; and 4) how to confirm identity of cannabinoids by optional ESI/MS using either high or low-resolution mass spectrometry.

Numerous crime laboratories have witnessed a surge in gun-related evidence submissions, leading to an increased demand for DNA testing and entry into the National Integrated Ballistic Information Network (NIBIN) for firearms-related investigations. Simultaneously, the forensic value of firearms analysis has substantially grown, owing to advancements in DNA technology and the expansion of the NIBIN database. Consequently, several forensic labs have established dedicated units specifically focused on comprehensive firearms analysis. This webinar showcases agencies that have implemented gun crime programs, highlights significant workflow modifications they have made, addresses questions regarding eligibility for the Combined DNA Index System (CODIS), and evaluates the return on investment in forensic examination of this crucial evidence.
