A novel, simple and sensitive method for the enantioseparation and determination of DL‐tetrahydropalmatine (DL‐THP) was developed using ACE in combination with partial filling technique and field‐amplified sample injection. A chiral selector, i.e. BSA, was used for the enantioseparation of DL‐THP in ACE. Effects of BSA concentration, pH and separation voltage on the effectiveness of the enantiomer...
In this study, an on‐line sample preconcentration technique, field‐amplified sample injection combined with water removal by electroosmotic flow (EOF) pump, was applied to realize a highly sensitive chiral analysis of β‐blocker enantiomers by MEEKC. The introduction of a water plug in capillary before the electrokinetic injection provided the effective preconcentration of chiral compounds. And then...
