摘　　要：利用库仑法测定水分的仪器,除了对测量电路方面有较高要求外,对试剂和水分反应所在的容器电解池也有较高要求。传统的单进样口电解池在进行纯水标定后进样口残留的水分会严重影响痕量水分检测的准确性,因此,本文提出一种双进样口电解池即可解决此问题。Instruments for the determination of moisture using the Karl Fischer coulometry have high requirements in terms of measurement circuits,but also in terms of the electrolytic cell of the vessel in which the reagents and the moisture reaction take place.The residual water in the traditional single inlet Electrolytic cell after pure water calibration will seriously affect the accuracy of trace water detection.Therefore,this paper proposes a double inlet Electrolytic cell to solve this problem.
