Abstract

Crosslinking experin(?)tnts for the chiral stationary phase OV-225-L-Val-t-butylamidewithin both fused silica and glass capillary columns have been carried out.Amino acid enantiomerswere separated on crosslinked columns by、both GC and SFC methods.In SFC,the α values of aminoacid enantiomers are independent of the density of the mobile phase,and they are hig her than thoseobtained by GC for the tested enantiomers with the same column due to the lower column tempera-ture used in SFC.
