1引言胶束电动毛细管色谱法（MECC）综合了反相高效液相色谱的分配机理和毛细管区带电泳的电渗及电泳机理，实现了对电中性物的分离。由于环糊精（CD）外表面具有亲水性，当其与胶束共存时，不能进入胶束，所以溶液存在三相即：胶束相、水相和CD相。异构体通过与CD形成不同稳定
1 Introduction Micellar electrokinetic capillary chromatography (MECC) combines the partitioning mechanism of RP-HPLC with the electrosorption and electrophoresis mechanism of capillary zone electrophoresis to achieve the separation of neutrals. Due to the hydrophilic nature of cyclodextrin (CD), when it coexists with micelles, it can not enter micelles, so there are three phases in the solution: micellar phase, aqueous phase and CD phase. Isomers are stabilized differently from CD formation
