Abstract:

Novel sulfonic acid and carbon chains of mixed-mode packing materials were synthesized through sulfonating polymer-encapsulated zirconia covered by a porous copolymer of olefinic hydrocarbon and divinylbenzene on its surface. This new packing material was evaluated in CEC, physical properties of these stationary phases were determined with SEM and IR. Chromatographic characteristics were evaluated in CEC.

Key words: Zirconia, Mixed polymer-encapsulated packings, Capillary electrochromatography(CEC)
