An exploration of experimental parameters in the analysis of epoxy resin by reverse phase liquid chromatography.
Reverse phase liquid chromatographic methods have been developed for the quality control of epoxy resin formulations. The results show that different formulations require different instrumental parameters for optimun separation and detection. Operating parameters required for the analysis of complex mixtures of epoxy resins, which include curing agents and diluents, are described in this paper. Parameters found to be critical are column temperature, solvent flow rate and gradient, and detector wavelength. Microprocessor parameters required to obtain reproducible data are also discussed.
