## Abstract An enantiomeric mixture of amino acids is derivatized to give the respective __N(O)__βperfluoroacyl alkyl esters which can be resolved directly by gas chromatography on a ChirasilβVal capillary column. The retention times, resolution numbers, and elution order are reported.
An improved method is described for the resolution of enantiomeric isopropyl esters of N-trifluoroacetyl-u-amino acids of nonbasic amino acids using N-docosanoyl-L-valyl-rbutylamide and N-octadecanoyl-L-valyl-t.-valine cyclohexyl ester as mixed chiral phases on 150-ft stainless-steel capillary colum
