چکیده

Separation of charged particles is a major problem in biological and chemical researches. There are several techniques for separate charged particles, one of them is electrophoresis. electrophoresis separates electrically charged particles by applying external uniform electric field. In recent  years,conventionalcross-form of geometry has been used for microchip electrophoresis. this paper represents  new cross-form geometry of microchip capillary electrophoresis with low separation time and high resolution and efficiency and are respectively equal to 100s,3.1,1166.5 while these values for conventional geometries are respectively equal to 120s,2.85,1004.8. these geometries are simulated by comsol.
