| Abstract: | A continuous two-dimensional open-tubular ion exchange/reversed phase monolithic column capillary electrochromatography system was developed.Reversed phase monolithic column was firstly synthesized in the end part of the capillary,then N-[3-(trimethoxysilyl)-propyl]-ethlenediamine was surface coated to the other part of the capillary.The separation of seven organic acids verified the effect on the separation of ion exchange in the open-tubular capillary.Rhizoma gastrodiae was separated to evaluate the syste... |
