The system implements a two-level distributed control, so it can not only suppress the noise effectively, but also accomplish such functions as magnifying, gathering and processing the ion chromatography signal precisely and intelligently, as well as displaying the spectrum of the ion chromatography signal. This article introduces the hardware construction and software design of the system and the principle of the system working. A measurement instance is also presented in this paper. The experimental result shows that the system runs well and the datum are reliable, so it can be applied in practical detection for ion chromatography completely.福建省科技资助项目(2001H081);; 厦门市科技计划资助项目(3502Z2001251
