title: Liquid chromatographic analysis of a potential polymeric-pendant drug delivery system for peptides. Application of high-performance size-exclusion chromatography, reversed-phase high-performance liquid chromatography and ion chromatography to the evaluation of biodegradable poly[(chloromethoxytrialanine methyl ester)phosphazenes].
abstract: A novel water-soluble polymer, poly[(chloromethoxytrialanine methyl ester)phosphazene] (poly-Tame), was characterized and evaluated using high-performance size-exclusion chromatography, gradient reversed-phase high-performance liquid chromatography and ion chromatography. These novel liquid chromatographic methods were validated for application to in vitro biodegradation experiments of poly-Tame in aqueous solutions. Results from method validation experiments are presented.
