molecular exclusion chromatography

基本解释

SEC2 was separated and purified successively by ultrafiltration, salting out with ammonium sulfate, ion- exchange chromatography and molecular exclusion chromatography.
发酵液经超滤浓缩、硫酸铵沉淀、阴离子交换色谱和分子筛色谱，获得了纯度为90%的SEC2，总收率23%。
Size-exclusion chromatography, as a special liquid chromatography, is used to determine the molecular weight distribution and preparatively separate the samples according to the molecular weight.
排阻色谱法做为一种特殊的液相色谱技术可用于分子量分布的测定及按分子量的不同进行的制备分离。
