PBD-coated zirconia

Carr and others have described the preparation and properties of polybutadiene (PBD) and polyethyleneimine (PEI), as well as aromatic polymer-coated and carbon-clad zirconia-based RP phases. The preparation of PBD-coated zirconia and the chromatographic evaluation of these phases have been described extensively by Carr, McNeff, and others [39 1]. From these studies, the authors conclude that at least for neutral analytes PBD zirconia-coated phases behave quite similar with respect to retention and efficiency compared to silica-based RP phases [42]. For polar and ionic analytes, however, substantial differences with respect to retention, selectivity, and efficiency have been reported [43].
