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 (C60) and the related higher fullerenes (C70, etc.) have been performed on the same stationary phase using eluents based on either n‐hexane or carbon dioxide.
