ABSTRACT

Supercritical uid chromatography (SFC) has long held an uncertain place among other separation techniques. However, recently, packed column SFC (pSFC) has become more attractive again to drug discovery [1-4] because it offers aqueous-free purication capabilities with a reputed green solvent (carbon dioxide), together with
