“…The problem is not only the temperature increase itself but also the formation of an undesired temperature gradient. Several groups [119][120][121] proposed numerical solutions and models to alleviate Joule heat effects on EOF and mass transport. Sweedler's group [122] followed the change by nanoliter-volume NMR thermometry and concluded that the temperature change due to the Joule heating has a significant effect on highelectric-field and large-diameter channels.…”

There is a great demand in separation technologies for faster and more effective analysis processes. Miniaturization is a suitable technique for satisfying this demand as reduction in size gives increased separation speed with higher efficiency. CEC is an electric-field-mediated separation technique where the liquid flow is generated by the electric field itself. The main advantage of using electric field over pressure for flow generation is the flat flow profile of the EOF; thus, CEC is one of the best candidates to construct a novel and high-efficiency microanalytical device. The aim of the present paper is to review the basic fabrication and bonding principles, as well as connection and system integration options for microfluidics-based electrochromatography. The physical structure and fluidic channel formation are critically evaluated, including glass microstructuring and fusion bonding. Recent developments in nanoflow measurements and the application of various flow control units are also extensively discussed.

“…Nusselt number versus ⁄ for purely electroosmotic flow Unlike hydrodynamic features, the study of thermal features of electroosmosis is recent. Maynes and Webb (2003) were the first who considered the thermal aspects of the electroosmotic flow due to an external electric field. They analytically studied fully developed electroosmotically generated convective transport for a parallel plate microchannel and circular microtube under imposed constant wall heat flux and constant wall temperature boundary conditions.…”

“…Knox [17] has explored the influence of Joule heating on efficiency in capillary electrophoresis. The fully-developed thermal transport for constant-property electro-osmotic flow in circular microtubes and parallel plate microchannels was previously explored for the case of negligible viscous heating [18]. Additionally, thermally fully-developed heat transfer has been explored for combined electro-osmotic and pressure driven, constant-property flow in a circular microtube under imposed constant wall heat flux boundary condition [19].…”
