| Abstract: | Ethylstyrene divinylbenzene coated TiO 2 (ES DVB TiO 2) was synthesized by at first bonding of vinyltriethoxysilane with hydroxyl group on titania and secondly by addition polymerization of vinyltriethoxysilane and ethylstyrene divinylbenzene The hydrophobic selectivity, absolute mobile phase sensitivity, and stability of the stationary phase were evaluated Finally, several kinds of practical separations were tested on ES DVB TiO 2 These examples showed that ES DVB TiO 2 synthesized in our laboratory was a good reversed phase stationary phase |

| Keywords: | ethylstyrene divinylbenzene coated TiO 2 stationary phase reversed phase chromatographic property hydrophobic selectivity absolute mobile phase sensitivity stability |
