... equations for the applied electric potential, electroosmotic flow field, Joule heating induced temperature field, and sample analyte concentration distributions as well. Scaling analysis was conducted to estimate time scales so as to simplify the mathematical model. Numerical computations were performed...

... 23 06 2009 Joule heating is an undesirable effect in capillary electrophoresis (CE). The heat generated by the electrical current leads to a temperature gradient along the separation channel and consequently affects the separation quality. Since the heat is inversely proportional...

...Proceedings of MNHT2008 Micro/Nanoscale Heat Transfer International Conference 1 Copyright © 2008 by ASME Joule heating on mass flux of electro-osmotic flow are discussed, respectively. The numerical results show the mass- flux increases with the increase of imposed positive pressure gradient...

... Focusing, Joule heating, Electrokinetic transport, Electrophoresis, Microfluidics Separation of charged species using CE is based on the principle of different electrical mobility of charged particles/macromolecules under an applied electric field. Due to low reagent and sample consumption and high...
