DiscovIR-GC™ Solutions for Forensic Science & Toxicology

DiscovIR-GC™ Solutions for Forensic Science & Toxicology

With DiscovIR-GC™, forensic drug chemists can rapidly and reliably distinguish between positional isomers of controlled substances, even in complex mixtures & matrices.

DiscovIR-GC™ yields enhanced (4cm-1) resolution solid-phase infrared spectra for the unambiguous identification of regioisomers, diastereomers, analogues, and other closely related compounds such as novel psychoactive substances, fentanyl analogues, pseudoephedrine/ephedrine, phenethylamines, and synthetic cannabinoids.

Compared to Mass Spectrometry, Infrared spectroscopy provides unique, structurally informative mass spectra. As a routine, hyphenated technique, when combined with parallel mass spectrometry, GC-FTIR/MS far exceeds the minimum requirements for drug identification, combining two SWGDRUG Category A and one Category B technique.

DiscovIR-GC™ alone, or with, parallel Mass Spectrometry provides a powerful “walk-up” instrument for unambiguous, uniquely defensible, drug identification, delivering detailed chemical information for differential analysis, at a higher level of specificity and selectivity than can be attained by (even HRAM tandem) Mass Spectrometry.

The DiscovIR-GC™ uses a spectral database search engine, to facilitate the rapid, unequivocal identification of sample unknowns against in-house, SWGDRUG or commercially available, solid-phase infrared and Mass Spectral Libraries.

Applications of DiscovIR-GC™ for Forensics analysis:

  • Simplified, unambiguous, uniquely defensible Drug Identification Platform for commercial forensic drug laboratories. The single, ‘one-stop shop’ platform for the analysis of complex drug mixtures (e.g., novel Psychoactive Substances and Synthetic Cannabinoids) reduces the potential for errors in automated assignment and is particularly useful for trace analysis, or when purification/fractionation for confirmatory NMR analysis is impractical or impossible.
  • Walk-up instruments for rapid confirmatory analysis in border-agency, airport/port authority, customs, or law-enforcement laboratories/facilities.
  • Confirmatory Forensic Analysis for border security, crime & counter-terrorism agencies
  • Unique intelligence platform for Forensic Investigators to determine the geographical origin and synthetic route of drugs
