Paper Abstract

A novel application of thick film technology (TFT) for creating a complete microstructure for capillary electrophoresis with contactless conductivity detection is presented. Elaborated microchip was made by bonding ceramic with a polymer. The photoimageable material (FODEL 6050, DuPont) was employed to creating microchannel (capillary) in the structure. It was due to merging thick film technology and photolithography. The contactless conductivity detector was equipped with two electrodes prepared with silver paste. The electrodes were separated from the microchannel by a dielectric layer. The functionality of the presented microchip was successfully verified by testing inorganic cations separation.
