Detection and Analysis of Seed-Based Toxins using Direct Analysis in Real Time Mass Spectrometry (DART-MS) and its Variants

January 2, 2022

Author(s)

Edward Sisco, Natalie Damaso, Liz Robinson, James Robertson, Thomas P. Forbes

Detection of seed-based toxins is a need for forensic chemists when suspected poisonings occur. In these instances, seeds are often first mashed to extract the toxins, eliminating the ability to identify the seed, and therefore toxin, based on physical

A Framework for the Development of a Targeted Gas Chromatography Mass Spectrometry (GC-MS) Method for the Analysis of Synthetic Cannabinoids

October 8, 2021

Author(s)

Edward Sisco, Amber Burns, Arun Moorthy

With the increased presence of novel psychoactive substances (NPSs) in casework, seized drug analysis has become more complex and challenging. To assist in addressing these challenges, a suite of targeted gas chromatography mass spectrometry (GC-MS)

Development and Evaluation of a Targeted Gas Chromatography Mass Spectrometry (GC-MS) Method for Analysis of Synthetic Cathinones

October 8, 2021

Author(s)

Edward Sisco, Amber Burns, Arun Moorthy

With the increased prevalence of novel psychoactive substances (NPSs), seized drug analysis has become more complex and challenging due, in part, to changing chemical structures and isomeric species. To assist in addressing these challenges a series of
