摘要：

A novel free-flow electrophoresis glass chip design with two-depth etched structures for the separation and fractionation of proteins is presented. The microfluidic structures etched in two depths enhance the flow characteristics inside the miniaturized device. A novel nine-port outlet interface enables the fractionation of the separated analytes. The separation and focussing of a protein sample Mixture demonstrated the ability of the new chip.
