Strategy for identification of new psychoactive substances in illicit samples using attenuated total reflectance infrared spectroscopy

Autor: K. Stypulkowska, K. Piorunska-Sedlak

Publikováno v: Forensic science international. 312

New strategy has been developed for the identification of novel psychoactive substances (NPS) in illicit samples. The methodology was based on the use of attenuated total reflectance Fourier transform infrared spectroscopy (ATR-IR). First pass screen
