【Abstract】 A new μTAS(micro total analysis systems) for biochemical analysis is introduced, including the design and fabrication techniques for the capillary electrophoresis (CE)chip,the microprocessor system and the initial experiment result. The new CE chip based on linear-arrayed electrode is capable to change the experiment conditions flexibly, such as separation time, distance and driving voltage etc, and to meet the needs of many separation. The control kernel of the system is single chip processor C8051F020, and many parallel ports for connecting high voltage system have been expanded. The new system has the characteristic of high integration, low power consumption and high expansibility, and a good example of extending many parallel ports to control high voltage apparatus flexibly is given.更多还原
