Abstract

Abstract: Avertical electrochemical detection for capillary electrophoresis was described.The detector consisted of the home-constructed micromanipulator and the electrochemical cell.The performance was evaluated by the determinations of dopamine, norepinephrine and epinephrine in the CEECsystem.The lowest detectable concentration was 1.0×10^-7 mol/Land the relative standard deviation was less than 5% for each of the compounds.

Key words: Capillary electrophoresis, Electrochemical detection, Catechol amine
