Abstract
A new rigid graphite-epoxy composite electrode for electrochemical detection in microchip electrophoresis is described. The end-column wall-jet detection design relying on tubular rigid composite working electrode shows favorably low noise level and high signal-to-noise ratio when compared to glassy carbon detector. The performance of rigid graphite-epoxy composite detector was compared to glassy carbon detector using dopamine and catechol as model analytes. The various parameters of the microchip electrophoresis-rigid graphite-epoxy composite detector were optimized. © 2006 WileY-VCH Verlag GmbH & Co. KGaA.
