| Abstract: | The technique of electric injection and seperation is one of the most important technology of Capillary electrophoresis analysis in microfludic chip. Through the voltage alteration, the direction and velocity of the sample's electroosmotic flow in the chip can be controled. Then the seperation efficiency and sensitivity can be examineed and detected. A conclusion about the best scheme of voltage controlling to this type of chip is drawn. |
