Title:
PRACTICAL DEVICE FOR CONTROLLING ULTRASMALL VOLUME FLOW
Document Type and Number:
WIPO Patent Application WO2000028315
Kind Code:
B1
Abstract:
A device for control of ultrasmall volume fluid flow used in the fields of electrophoretic separation, chemical analysis, and microchemical reactions has a substrate defining a capillary channel and integrated external electrodes to control electroosmotic flow. The channel geometry and integrated external electrode proximity reduce the voltage required for control of flow. Longitudinal electrodes provide electrophoretic separation of components. High dielectric material between the integrated external electrode and capillary reduces the voltage required for the control of flow. Real-time flow monitoring and capillary channel surface coating enhance the control of flow.
