"High-performance liquid displacement chromatography of enantiomers on a chiral poly-L-valyl-based stationary phase"

A direct enantiomer separation according to the displacement mode of liquid chromatography has been developed on a silica-based stationary phase bearing as chiral selectors poly-L-valyl groups. Milligram amount resolution of DL-methionine β naphthylamide was accom plished on two analytical size columns using methanol-containing acetate buffer as the carrier and DL mande lie acid dissolved in the carrier as the displacer.
