Abstract: 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 2083 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.

Key words: Valinomycin, Capillary gas chromatography, Stationary phase
