Description

Analysis Note The rapid growth of the cannabis testing market has prompted the development of equally rapid methods to analyze the active ingredients. Shown here is the separation of cannabis compounds on an Ascentis Express RP-Amide column. The selectivity, and therefore resolution, is unique to the amide bonded phase chemistry. 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.
