Octadecyl-functionalized monolithic silica capillary columns with inner diameters of 100 and 200 micrometers for reversed-phase capillary liquid chromatography were prepared in the fused-silica capillary via sol-gel process. Their performance was evaluated and compared by the separation of alkylbenzenes (toluene, ethylbenzene, propylbenzene, butylbenzene). The column back pressure and linear velocity of mobile phase were investigated. The results show that the monolithic silica capillary columns exhibit good performance for the separation of alkylbenzenes.
