Abstract
Chromatographic separations and resolutions of racemic mixtures and diastereoisomers are enhanced by simultaneously employing an enantiomeric, chiral stationary phase (CSP) and an enantiomeric, chiral mobile phase additive (CMPA) bearing a stereoisomeric relationship to the CSP but having the opposite chirality are enhanced relative to the use of either a CSP or a CMPA alone. Specific CMPA compositions having the structural formulas ##STR1## are also disclosed.
