Applications of chiral supercritical fluid chromatography

Abstract

Nowadays polysaccharide chiral stationary phases are very popular and this originates for many reasons: (1) their wide applications window, (2) numerous different chemistry availability either in coated or in immobilized versions, and (3) large loading capability useful for preparative scale. Indeed chiral separations remain a hot topic (particularly in the pharmaceutical market) and in this field supercritical fluid chromatography is emerging rapidly. However, its use is more complex than high-performance liquid chromatography. The presented example illustrates analytical scale chiral separation method development and the effect of each operating parameter, i.e., flow rate, outlet pressure, and temperature variations on a chiral separation.
