甲醇水分的测定是甲醇产品中一个重要的测定项目，目前有关标准中测定甲醇水分的方法卡尔·费休法。该方法是用卡尔·费休试剂(碘、二氧化硫、吡啶和甲醇组成的溶液)与样品中的微量水定量反应,然后用已知水含量的卡尔·费休试剂来测定样品中的微量水分,该方法操作繁琐,且卡尔试剂不易保管和有毒。

The determination of methanol moisture is an important measurement item in methanol products. At present, the only method for determining the moisture content of methanol in relevant standards is the Karl Fischer method. This method uses Karl Fischer reagent (a solution consisting of iodine, sulfur dioxide, pyridine, and methanol) to quantitatively react with a trace amount of water in a sample, and then uses a Karl Fischer reagent with a known water content to determine the trace moisture in the sample. This method is cumbersome to operate, and Karl reagent is not easy to keep and toxic.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd., developed a new 2020 special capillary column for practical application. This instrument is very popular due to its simple and flexible operation and high accuracy of data.
