名稱：填充柱
固定相：專用
型號：HH-EO

環(huán)氧乙烷水含量采用F水份儀進(jìn)行測定,該儀器操作簡便,快捷,精密度高,分析結(jié)果準(zhǔn)確.但在實際工作中,環(huán)氧乙烷水含量測定的結(jié)果重復(fù)性卻不好,差值經(jīng)常超出方法規(guī)定,同時與生產(chǎn)裝置的工藝控制不相符,無法反映出樣品真實的水含量.

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司采用氣相色譜法通過試驗驗證,確定環(huán)氧乙烷水含量測定時應(yīng)做到:采樣時充分置換采樣鋼瓶;進(jìn)樣方式由夾套移液管改為用7號長針頭接鋼瓶直接進(jìn)樣;.在這樣的條件下,環(huán)氧乙烷水含量測定結(jié)果的重復(fù)性有了很大的提高,差值〈0.001%,達(dá)到分析方法的要求,了分析結(jié)果的準(zhǔn)確性.

Packed column for ethylene oxide water content determination
Packed column for ethylene oxide water content determination Details:

Name: Packed column
Stationary phase: dedicated
Model: HH-EO

The water content of ethylene oxide is determined by the F moisture meter. The instrument is easy to operate, fast, with high precision and accurate analysis results. However, in actual work, the repeatability of the results of the measurement of ethylene oxide water content is not good. The absolute difference often exceeds the method regulations, and at the same time does not match the process control of the production device, and cannot reflect the true water content of the sample.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has adopted gas chromatography to pass the test and verification, and when determining the content of ethylene oxide water, it should: fully replace the sampling cylinder during sampling; change the sampling method from jacketed pipette to use The 7 gauge long needle is connected to the steel cylinder for direct injection; Under such conditions, the repeatability of the measurement results of the ethylene oxide water content has been greatly improved, and the absolute difference is <0.001%, which meets the requirements of the analytical method and ensures The accuracy of the analysis results.
