Introduction
Although pure ethanol has been used as the mobile phase in
chiral separation with polysaccharide-based chiral stationary
phases (CSPs) as early as 1973 by Hesse and Hagel [1],
once these materials became commercially available, pure
polar organic solvents, such as methanol, ethanol, 2-propanol,
acetonitrile, etc., were avoided (considered incompatible)
in HPLC enantioseparations with polysaccharidebased
CSPs. Before the year 2000, the use of polar organic
mobile phases in combination with these CSPs has been
reported in only very few studies [2–5]
