甲醇水分的測定是甲醇產(chǎn)品中一個重要的測定項目，目前有關標準中測定甲醇水分的方法卡爾·費休法。該方法是用卡爾·費休試劑(碘、二氧化硫、吡啶和甲醇組成的溶液)與樣品中的微量水定量反應,然后用已知水含量的卡爾·費休試劑來測定樣品中的微量水分,該方法操作繁瑣,且卡爾試劑不易保管和有毒。

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.
