Abstract

This paper describes an in situ preparation of a chiral stationary phase on silica gel for the resolution of amino acid racemates. A column prepared from a Waters Radial-Pak cartridge was useful for the rapid and efficient resolutions of some aromatic α-amino acids. Separation factors (α) of 2.8, 3.6, 4.2 and 4.6 were observed for phenylalanine, tyrosine, dopa and tryptophan, respectively. A plate count as high as 1700 plates/meter was observed at room temperature for d/ l-dopa.
