Fractionation of plant extracts by supercritical fluid extraction and direct introduction in capillary gas chromatography using a programmable temperature vaporizer

, 1999
A simple procedure to improve the sensitivity achievable in the analysis of supercritical fluid extracts of complex matrices is proposed. The method involves the offline coupling of supercritical fluid extraction and gas chromatography (GC) in such a way
