Abstract

Fast and efficient separations of chiral stereolabile compounds were obtained at very low temperature on a π‐acid chiral stationary phase (R,R‐DACH‐DNB) using carbon dioxide‐based mobile phases containing alcoholic polar modifiers.

Furthermore, efficient separations of the newly discovered spherical carbon cluster buckminsterfullerene (C~60~) and the related higher fullerenes (C~70~, etc.) have been performed on the same stationary phase using eluents based on either n‐hexane or carbon dioxide.

A sensitive enantioselective high-performance chromatographic (HPLC) method was developed and validated to determine low levels of (-)-R and (+)-S-albuterol in plasma. Baseline resolution was achieved by using a teicoplanin-based chiral stationary phase with a polar organic mobile phase consisting o
