| Abstract: | A new design of electrochemical detector (ED) for high-performance capillary electrophoresis (HPCE) was described. A HPCE/ED Nafion interface allows the separation potential only applied across the separation capillary, and the strong electroosmotic flow generated in the separation capillary can force the solvent and analyte zones passing through the detection capillary freely. This configuration effectively isolates the interference of the detector from the high applied voltage via the resistance of the detection capillary. An example was shown in a micellar electrokinetic capillary chromatography of several phenols and hydroquinone with a detection limit of 30 attomole. |
