摘　　要：Fused-silica capillary column containing valinomycin and OV-1701(mass ratio 15∶85) as a new stationary phase component was(prepared.) The column was thermal stable below 176 ℃,the average value of McReynold constants was 157,and its column efficiency was 2 083 plate/m when the retention factor was(2.20.) Some aromatic(positional) isomers and chiral compounds,such as cresol,xylene,nitrotoluene,D,L-valine,D,L-leucine,(±)isopinocampheol,(±)roseoxide,(±)dihydrocaruvyl acetate were separated.It showed excellent(selectivity) toward aromatic positional(isomers) and chiral compounds.Fused-silica capillary column containing valinomycin and OV-1701 （ mass ratio 15 ： 85 ） as a new stationary phase component was prepared. The column was thermal stable below 176 ℃, the average value of McReynold constants was 157, and its column efficiency was 2 083 plate/m when the retention factor was 2.20. Some aromatic positional isomers and chiral compounds, such as cresol, xylene, nitrotoluene, D, L- valine, D, L-leucine, （ ± ）isopinocampheol, （ ± ）roseoxide, （± ） dihydrocaruvyl acetate were separated. It showed excellent selectivity toward aromatic positional isomers and chiral compounds.
