摘要
在《GB/T 14571.2-2018工业用乙二醇试验方法第2部分:纯度和杂质的测定气相色谱法》提供的典型操作条件的基础上,通过对程序升温、分流比、进样量和载气流速等色谱操作条件的确认和优化,改善了色谱分离效果。
Based on GB/T 14571.2-2018 Industrial Ethylene Glycol Test Method Part 2:Determination of Purity and Impurities by Gas Chromatography,the chromatographic operating conditions such as temperature programmed work,split ratio,injection volume and carrier gas flow rate were confirmed and optimized,the chromatographic separation effect was improved well.
