Abstract

In this paper, optimum Peclet number for the measurement of electroosmotic mobility with controlled errors in current-monitoring method was systematically investigated. A simple silicon based microchannel was fabricated for the experiments. Experiments and theoretical analysis of electroosmotic flow of both simple (NaCl) and complex electrolytes (concentrated Tris-Borate-EDTA buffer) was conducted to investigate the Peclet number effects on the error of electroosmotic mobility measurements. The results show that minimum Peclet number exist for desired accuracy.
