Direct Chiral Resolution of Optical Isomers of Diltiazem Hydrochloride by Packed Column Supercritical Fluid Chromatography

Packed column subcritical and/or supercritical fluid chromatography (p-sub or pSFC) has been used as a powerful chiral separation technique, whereby a mobile phase produces low viscosity, a high diffusion coefficient, and a solvating power. P
