Detection of Organic Gunshot Residue Using Capillary Microextraction of Volatiles with Cryofocusing

Technical Note Date July 2017 Purpose Researchers at Florida International University’s (FIU’s) International Forensic Research Institute evaluated the capability of capillary microextraction of volatiles (CMV) to extract the volatile organic compounds (VOCs) that constitute organic gunshot residue (OGSR) on the…

Evaluation of Existing Technologies for Novel Analysis and Probabilistic Interpretation of Organic Gunshot Residue

Technical Note Date July 2017 Purpose   Firearms exposure has traditionally been monitored by screening for the presence of inorganic particles prevalent in gunshot residue (GSR). These inorganic compounds are associated with the primer in ammunition. Recent research efforts have…

Fentalogs – Pharmacology, Toxicology & Analytical Approaches

← Back to Series  We will review the chemistry of fentanyl, its analogs and precursors, their pharmacology and relative potency, and approaches to identifying novel fentanyl analogs in forensic toxicology casework. Fentanyl and its analogs, sometimes called “The Fentalogs”, are…
