Molecular spectroscopy in forensics

The right analytical techniques provide answers to confidently identify samples from opioids to paint chips to counterfeit paper. Whether your lab is consumed by the opioid crisis or busy investigating other serious crimes, having the right instrument(s) can help move cases from the investigation stage to solved.

The best techniques for identifying and analyzing chemical data are Raman and FTIR spectroscopy. These techniques can be used together or independently, and work with a variety of samples types, offer different sample prep options and confirm sample information by using libraries. See examples below on how to solve the most common forensic cases or talk to a specialist about the analytical needs of your lab.

Distinguishing isomers of fentanyl analogs using FT-Raman

Illicitly manufactured fentanyl and fentanyl analogs (FAs) is becoming a major driver of opioid overdose. We have demonstrated that FT-Raman spectroscopy is a safe, fast, and complementary technique for the detection and identification of powders and other apprehended materials including fentanyl.

In this note, two examples of distinguishing FA isomers using FT-Raman spectroscopy are described. A pair of constitutional isomers: butyryl fentanyl and isobutyryl fentanyl, and a pair of geometric isomers: cis- and trans3-methyl fentanyl were analyzed by FT-Raman.
