Description
Analysis Note
Synthetic cannabinoids (e.g. "Spice") are a type of designer drug that provide a cannabis-type high. New synthetic cannabinoids are continually being introduced as suppliers tweak the molecular structures. The ability to rapidly and reliably identify the continually changing population of these compounds is a significant analytical challenge facing forensic chemists. A rapid separation of eight of these compounds on Ascentis Express F5 column is shown here. Cerilliant CRMs provided reliable identification and quantification.
