haohanHH-Ethanol-30专用毛细管柱测定乙醇中的水分2020新品2m*3mm

           目前乙醇中水分的测定的方法很多，主要有气相色谱法，卡尔费休法，仪器快速检测法等。这些方法各有各的优点，也各有各的不足之处。
            国家规定弗休法测定痕量水分的标准分析方法、具有灵敏、准确、应用广泛等一系列优点。但它的致命弱点是难以弥补的,这就是该法使用的试剂都是有毒试剂,对操作人员的身体健康有严重损害,用过的试剂对环境可造成较为严重的污染。另外,弗休法滴定试剂均要进行脱水处理、比较麻烦,而且试剂价格昂贵,易受环境湿度影响,对操作要求也比较高。

 At present, there are many methods for the determination of moisture in ethanol, including gas chromatography, Karl Fischer method, and rapid instrument detection. Each of these methods has its own advantages and disadvantages.
The standard analytical method for the determination of trace moisture by the Hughes method stipulated by the state has a series of advantages such as sensitivity, accuracy, and wide application. However, its fatal weakness is difficult to make up for. This is that the reagents used in this method are toxic reagents, which seriously damage the health of operators, and used reagents can cause more serious pollution to the environment. In addition, the dehydration treatment of the Fuxiu titration reagents is all troublesome, and the reagents are expensive, susceptible to environmental humidity, and require high operating requirements. Zh

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. keeps pace with the times and uses the new 2020 special capillary column method to determine the moisture in industrial ethanol. The column efficiency is high, the separation is good, the external standard is quantified, and the results are satisfactory.
