Coupling of Supercritical Fluid Extraction with Chromatography

Abstract

Coupling methods between supercritical fluid extraction (SFE) and various chromatographic techniques have been reviewed. Developments using supercritical fluids in chromatography have been tremendous and a confirmation of the usefulness of this technique (called supercritical fluid chromatography (SFC)) has been evidenced by many scientists. Another field using supercritical fluids in analytical processes is SFE. Since SFE has many advantages compared to conventional solvent extraction method, such as faster and better controllability of conditions, no requirements for solvent waste and lower cost, popularity has been recently increasing
