摘要
The preparation of capillary electrochromatography column for chiral separation with β-cyclodextrin derivatized Pancreatin was imvestigated, which had three steps, synthesis of β-cyclodextrin derivated pancreatin, the modification of the capillary internal surface and the covalent binding of β-cyclodextrin derivated pancreatin on the capillary internal wall. β-cyclodextrin derivated pancreatin was synthesized using β-cyclodextrin and protein in the presence of ethylene glycol diglycidyl ether (EGDE) in boric acid buffer at pH = 8.7. Amino group was coated on the internal surface of the silica capillary by sot-gel technology using triethoxylmethylsiloxane and ( 3-aminopropyl ) trimethoxysiloxane. Covalent binding of β-cyclodextrin derivated pancreatin was performed by glataraldehyde. Chlorpheniramine, phenylalanine and troopine were separated baseline by β-cyclodetrin derivated pancreatin in capillary electrochromatography.
