环氧乙烷水含量采用F水份仪进行测定,该仪器操作简便,快捷,精密度高,分析结果准确.但在实际工作中,环氧乙烷水含量测定的结果重复性却不好,差值经常超出方法规定,同时与生产装置的工艺控制不相符,无法反映出样品真实的水含量.

浩瀚色谱（山东）应用技术开发有限公司采用气相色谱法通过试验验证,确定环氧乙烷水含量测定时应做到:采样时充分置换采样钢瓶;进样方式由夹套移液管改为用7号长针头接钢瓶直接进样;.在这样的条件下,环氧乙烷水含量测定结果的重复性有了很大的提高,差值〈0.001%,达到分析方法的要求,了分析结果的准确性.

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.
