Evaluating a Statistical Method for Comparison of Mass Spectra of Novel Psychoactive Substance
Identification of novel psychoactive substances (NPS) based on comparisons of electron-ionization (EI) mass spectra continues to pose challenges in seized drug analysis. In this webinar, a method to statistically compare EI mass spectra is described, and an application of the method to distinguish several structural and positional isomers of NPS analogs are demonstrated.
This webinar was hosted by the NIJ Forensic Technology Center of Excellence on July 25, 2024.
