Complementary high-speed liquid chromatographic techniques have been combined with infrared spectroscopy for the characterization and analysis of polyoxyethylene fatty acid surfactants and their decomposition products in industrial process waters. The combination of molecular sieve chromatography and infrared spectroscopy offers a selective and simple method for the analysis of trace concentrations (detection limit approx. 0.05-0.1 ppm) of these surfactants. Liquid-solid and reversed-phase chromatography have proven useful for the characterization and analysis of free fatty acids. Some of the parameters that affect the reversed-phase separation of fatty acids are discussed.
已将互补的高速液相色谱技术与红外光谱相结合，用于工业生产用水中聚氧乙烯脂肪酸表面活性剂及其分解产物的表征和分析。分子筛色谱法与红外光谱法相结合，为分析这些表面活性剂的痕量浓度（检测限约为0.05 - 0.1 ppm）提供了一种选择性且简便的方法。液固色谱法和反相色谱法已被证明对游离脂肪酸的表征和分析很有用。文中讨论了一些影响脂肪酸反相分离的参数。
