标准摘要
[中文适用范围]： 规定了根据分子大小或分子量和极性将酚醛树脂分离为其组分化合物的三种色谱方法：凝胶渗透色谱法、极性和非极性柱上的高效液相色谱法。 适用于可溶于所用溶剂和溶剂混合物的酚醛树脂。 该测试对于产品表征和研究很有用。 [外文原描述]： 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.
英文名称Plastics — Phenolic resins — Separation by liquid chromatography
