摘要
研制了一种微量水份分析仪,仪器采用卡尔-费休尔试剂,以库仑滴定原理测量物质所含表水和结晶水。介绍了仪器的主要电路设计。用两种方法测量了仪器的准确度,相对误差均不超过3％。
A trace water analysis instrument is described The principle of measurement is based on coulometric titration using KF reagent. The instrument can measure trace amounts of water (including crystallization water) in materials for quality control. The designs of main electric circuits are described. The accuracy of the instrument is teated with two methods The relative deviations are no more than 3%.
