Fused－silical capillary columns containing heptakis (2、3、6－tri－o－pentyl)-β-cyclodextrin and dibenzo-18-crown-6 were prepared.By studying the selectivity of mixed stationary phases for some solute pairs.as well as comparing with the heptakis (2、3、6-tri-O-pentyl)-β-cyclodextrin and thedibenzo-18-crown-6 used as individual stationary phase、the synergistic effects were observed.These effects were affected by the column temperature.mixed ratio and linear velocity of carrier gas.
