通过ＨＰＬＣ结合旋光光度定量的方法，探讨了流动相添加剂β－环糊精及其２，６－二甲基衍生物的吸附性质。结果表明β－环糊精在ＯＤＳ固定相上不吸附，而其２，６－二甲基衍生物则呈典型的单分子层吸附。
The adsorption properties of mobile phase additive β-cyclodextrin and its 2,6-dimethyl derivatives were discussed by means of HPLC combined with optical rotation photometry. The results showed that β-cyclodextrin did not adsorb on the ODS stationary phase, while its 2,6-dimethyl derivative showed typical monolayer adsorption.
