Abstract
A rapid method is described for the analysis of Cannabis products by supercritical fluid chromatography (SFC) coupled to atmospheric pressure chemical ionization-mass spectroscopic (APCI-MS) detection. The method had a shorter analysis time than GC-MS methods, without the need for derivatization prior to analysis. It was also faster than HPLC methods, with better resolution and definitive identification. Linearity of detector response to cannabidiol, delta 8-tetrahydrocannabinol, delta 9-tetrahydrocannabinol and cannabinol was established, the detection limits for mass on column being 0.55 ng, 1.20 ng, 0.69 ng and 2.10 ng respectively. The technique offers a means by which Cannabis products can be definitively identified in a single chromatographic run. Application to casework samples is described.
