Abstract: A two-dimensional separation platform of capillary isoelectric focusing(CIEF)-capillary zone electrophoresis(CZE) for proteins was constructed by a microdialysis hollow fiber interface. The interface provided ease of fabrication,speed of mass delivering and convenience of column switching. Chrome c was selected to demonstrate the 2D separation systems feasibility and resolving performance. The 2D separation system was found to greatly increase the resolving power and overall peak capacity over those obtained for either dimension alone.

Key words: Microialysis hollow fiber membrane interface, Two-dimensional separation platform, Capillary isoelectric focusing, Capillary zone electrophoresis
