Preparative Separation by SFC

Preparative SFC

Preparative Separation Typically medicinal cannabis production involves an initial extraction from the flower bud material using Supercritical Fluid Extraction (SFE), solvent extraction or similar technique to produce a concentrate of terpenes and cannabinoids. The basic SFC system comprises a high-pressure liquid CO2 pump, co-solvent pump (for gradient work), separation column, typically a cellulose column with […]

Analytical Separation Of Cannabinoids

Analytical Separation of cannabinoids -min

Cannabinoid Analytical Separations Cannabinoid Analytical and Preparative Separations Supercritical Fluid Chromatography (SFC) is a relatively new technique that offers several advantages including faster run times, better resolution and more concentrated separations. The limitations of SFC are: it has only been proven on small molecular groups and gradient development is more complicated than for HPLC. The […]
