Abstract
Fused-silica 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 the dibenzo-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.
