【Abstract】 An automatic capillary electromatographic system based on modular concept has been designed. Three different separation modes(CEC,CE and μHPLC) can be performed through different combinations. Pressurized CEC with both voltage gradient and mobile phase gradient has been realized. The flow path is specially designed for CEC separation and a zero dead volume injection valve is used. A flow splitter suitable for gradient elution of pressurized CEC was designed and fabricated. The instrument is innovative and has high application values for micro analysis.更多还原
