Specifies three chromatographic methods for the separation of phenolic resins into their component compounds according to molecular size or molecular weight and polarity: gel-permeation chromatography, high-performance liquid chromatography on polar and on non-polar columns. Applies to phenolic resins that are soluble in the solvents and solvent blends used. This test is useful for characterization of products and for research.
