摘　　要：与常用的双电极,双脉冲激励方式不同,本文设计一种四电极,直流恒电流激励方式的新型离子色谱电导检测系统,有效地简化了电路结构,精确并且智能化地完成离子色谱信号的采集、放大、处理、谱图显示等功能.介绍了该检测系统的基本原理及硬件设计.实验结果表明系统运行良好,测量结果准确.Being different from bipolar pulse technique, a new type conductivity detection circuit system applying constant current source for ion chromatography was designed which effectively reduces the complexity of bipolar pulse technique, accurately and intelligently completes the signal amplification, collection, processing and spectrum displaying. In this article the detection principle and the hardware of the system were described and the experimental results with accurate and reliable measurements were shown.
