目前作為產(chǎn)品分析采用氣相色譜法測(cè)定工業(yè)氯仿中的微量水分，還沒(méi)有方便快捷、實(shí)用的國(guó)標(biāo)方 法．滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，在這方面作了一些探索工作．由于氯仿與水形成二元共沸物，很難得到純凈氯仿，導(dǎo)致分析其中水分含 量要采用內(nèi)加法這一特殊定量方法．采用氣象色譜方法不僅簡(jiǎn)便、快速，靈敏度高，且重現(xiàn)性好，是測(cè)定工業(yè)氯 仿中微量水分的一種行之有效的新方法．



Determination of trace moisture in industrial chloroform
Determination of trace moisture in industrial chloroform Details:

Name: Packed column
Specification: 2m*3mm
Model: HH-Chloroform2
Application: Determination of trace moisture in industrial chloroform

At present, as a product analysis, gas chromatography is used to determine trace moisture in industrial chloroform, but there is no convenient, fast and practical national standard method. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has done some exploratory work in this area. Since chloroform and water form a binary azeotrope, it is difficult to obtain pure chloroform, which leads to the analysis of the water content in the special quantitative method of internal addition. The gas chromatography method is not only simple, rapid, highly sensitive, and reproducible, it is an effective new method for the determination of trace moisture in industrial chloroform.
