Abstract
A novel design approach for optimizing the shape of the microfabricated pillar columns [1] for Capillary Electro Chromatography (CEC) is presented. The approach leads to the introduction of a new foil shape, and "equivalent width" definition as a geometry independent method to place column structures within the microchannel. Microfluidic flow simulations were performed for electroosmotic flow (EOF) case with a non-retained marker for evaluating the performance of the foil definition over other alternatives (diamond and hexagon) from literature [2]. Foil shape yielded 12-13% lower plate height values. Applying equivalent width definition for placement of this structure resulted additional 15-18% decrease.
