Using a standard photolithographical procedure, chemical wet etching and thermal diffusion bonding technology, a chemical analysis device for Capillary Electrophoresis(CK) has been microfabricated on a planar glass substrate with a cross-column geometry. The channels on the microchip substrate are about 50μm deep and 150μm wide. By employing amino acids derived from 2,4-DiNitroFluoroBenzeri (DNFB) on CE chip channels, the sample manipulating system is studied based on the principle of electrodynamics.
