In this study we investigate the recently reported use of water-containing modifiers for separation and purification of hydrophilic compounds by supercritical fluid chromatography. Improved peak shape is obtained for a variety of glycosides and otherwise hydrophilic compounds when 5% water is added to the methanol co-solvent used in SFC separations, and examples of the use of this approach in preparative SFC purifications are presented.
