| 摘 要： | 气相色谱法是最常用的混合工质组元浓度分析方法。针对氢氟烃二元混合物的特点,本文搭建了气相色谱法混合工质组分分析实验台,测定了9种氢氟烃二元混合物组元质量分数与峰面积百分比的对应关系。讨论了气相色谱法混合工质组分分析的理论方法,比较了2种标准曲线函数模型对实验数据的再现精度,本文提出的校正因子为变量的模型对实验数据的再现性较好,平均绝对偏差小于±0.25%,满足热物性研究对混合物组元成分分析的实验要求。

| Abstract: | Gas chromatographs are often used to analyze mixture composition in thermophysical property measurements. A new composition analysis method was developed based on the gas chro-matograph and the characteristics of binary hydrofluorocarbon (HFC) mixtures, and was used to analyze nine binary hydrofluorocarbon mixtures related to the mass fraction composition and the ratio of peak area. A new standard curve model for the data correlation was developed with the response factor as a variable. The model more accurately represented the experimental data than a third-degree polynomial expression. The average absolute deviation (AAD) of the present formula for each sample was less than 0.25%. |
