卡尔·费休库仑法水分测量技术及其应用研究

Moisture Measurement Technology by Using Karl-Fischer Coulometry and Its Application Study

运用卡尔·费休库仑法,对日本三菱公司的CA-06水分测定仪不能直接检测的固体、油品和气体中水分含量进行检测技术研究。组建了固体、油品及气体水分检测系统,试验验证检测结果准确、可信,使CA-06水分测定仪应用范围得以拓宽。将建立的检测技术应用到泡沫材料、气相白碳黑、桂树脂及高纯氢气中的水分含量检测,均获得了较好的检测结果。

The moisture measurement of undissolved solid, grease and gas is studied based on the principle of Karl - Fishcher coulometry, which cannot be conducted directly by CA - 06 moisture equipment. Through online of carrier gas, evaporating apparatus and host machine of moisture detector, a moisture detecting system of solid, grease and gas is constructed. The application of CA - 06 moisture equipment has been successfully expensed. The moisture measurement has good repeatability and reliable analytic results as well as high degree of accuracy. Experimental studies on foam materials, fumed silica, polyurethane foam and silicone as well as higher pure hydrogen are conducted by this technique and excellent measurement results are obtained.
