| | Electroosmotic Pumping of Nonconducting Liquids by Viscous Drag from a Secondary Conducting Liquid | | Authors: | A. Brask, G. Goranovic and H. Bruus | | Affilation: | Technical University of Denmark, DK | | Pages: | 190 - 193 | | Keywords: | viscous pump, CFD simulations, nonconducting liquids, EOF | | Abstract: | A novel electroosmotic pump design relying on two-liquid viscous drag to pump nonconducting liquids is presented and analyzed theoretically. A conducting pumping liquid driven by electroosmotic flow (EOF) drags a nonconducting working liquid by viscous forces. In particular liquids such as oil or ethanol, which normally cannot be moved by EOF, can be pumped. This allows for new types of analysis in the field of micro Total Analysis Systems which may prove important in the drug industry and for environmental monitoring. The flow rate/pressure (Q-p) characteristic of the pump depends largely on achievable geometrical dimensions. This paper presents a complete theoretical and modeling study of the novel design. |  | View paper | | ISBN: | 0-9728422-0-9 |
