摘要
本文介绍了气相色谱法分析丙烯中微量一氧化碳、二氧化碳含量影响分析结果准确性的原因,通过改进方法增大进样体积、调整阀切时间以及规范进样方法,提高分析结果准确性和精密度。
This article describes the reasons why the gas chromatography of trace carbon monoxide and carbon dioxide in propylene affects the accuracy of analytical results,the accuracy and precision of the analysis results were improved by improving the injection volume,adjusting the cutting time of the valve and standardizing the injection method.
