摘　　要：研制了一种新型离子色谱电导检测器。采用方波电压为激励信号 ,在适当时刻用同步脉冲触发采样 ,可消除电极极化和双层电容对电导测量的影响 ,提高仪器准确度。A new conductivity detector for ion chromatography is presented. The square wave is used as stimulating signal and the sampling is triggered by synchronization pulse at suitable times. By using these measures, the effects of double layer capacitance and polarization on the measurement are eliminated and the accuracy is improved.
