Description

Analysis Note Synthetic cannabinoids (e.g. "Spice") are a type of designer drug used to get 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 in the blood or urine suspected users is a significant analytical challenge facing forensic chemists. Here is shown the selectivity provided by C18 phase chemistry on an Ascentis Express C18 column with UV detection. Cerilliant CRMs provided reliable identification and quantification.
