Preparation and Evaluation of Polymer-encapsulated Zirconia-based Packing Stationary Phase for HPLC

Abstract

Abstract: Novel alkyl and aromatic polymer-encapsulated zirconia-based packings for HPLC stationary phase were synthesized by radical polymerization of olefinic hydrocarbon and divinylbenzene with vinyl-modified zirconia in solution. SEM and ¹³C CP/MAS NMR were used to determine the physical properties of these stationary phases. Chromatographic characteristics were evaluated, and pH stability was also examined. Its superior performance for the separation of mixtures of polycyclic aromatic hydrocarbon and anilines were demonstrated.

Key words: Zirconia, Cross-linking polymer-encapsulated packing stationary phase, Liquid chromatographic column filler
