NEW ULTRAHIGH EFFICIENCY, SUPERFICIALLY POROUS PARTICLE (SPP) CHIRAL PHASES FOR LIQUID CHROMATOGRAPHY

摘要

The present invention relates to a novel stationary phase support for liquid chromatographic chiral separations. The specific combination of the special underlying support material and certain classes of known chiral selectors according to the invention produces far superior chiral (enantiomeric) separations than those obtained on any conventionally known supports. These chiral (enantiomeric) separations are enhanced in terms of significantly higher efficiencies (theoretical plate numbers), higher resolutions (Rs), shorter retention times and either equivalent or slightly higher selectivities than those obtained on conventional supports.
