Descrizione
Risultati analitici
Synthetic cannabinoids (e.g. "Spice") are a type of designer drug that provides 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. The rapid, efficient UHPLC separation a set of these compounds on a Titan C18 column is shown here. The highest grade LC-MS solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant CRMs provided reliable identification and quantification.
