补充资料:色层分离
色层分离 chromatography 利用充填多孔性固体颗粒的填充柱,对液体或气体混合物中各组分的吸附性或溶解度等方面的差别,实现物理和化学性非常相近的组分间分离的方法。又称色谱法。属于传质分离过程。填充柱是分离装置的主体,柱内充填多孔性固体颗粒,如吸附剂,称固定相。流过填充柱的多组分料液或混合气体,称为流动相。流动相通过填充柱时,物料中各组分因溶解度、吸附性等方面的差异,经过多次差别分配。易分配于固定相的组分,在柱内的移动速度慢,难分配于固定相的组分,移动速度快,从而使各组分逐步分开,最后实现较完全的分离。色层分离可用于从分子量很小的气体到分子量极大的蛋白质、核酸等各种混合物的分离。已逐渐推广到工业生产中,如生物活性物质的提取、重稀土金属的分离。 |
