摘要
利用气相色谱法采用HP-plotAl2O3S毛细管色谱柱,以1,1,1,2-四氟乙烷(R-134a)为对照品,测定了氟氯烃类物质(CFCs)相对于R-134a的相对质量校正因子,并考查了不同浓度下校正因子的差异。该方法准确、快速、简便,测定结果可直接应用于制冷剂中CFCs类物质含量的测定,同时为气相色谱法在无标准对照品的情况下直接准确测定CFCs类样品提供了重要数据支持。
The relative mass calibration factors of CFCs had been determined by GC with HP-plot Al2O3 S capillary column using 1,1,1,2-tetrafluoroethane （R-134a） as contrast. The difference in the relative mass calibration factors of CFCs at different concentrations had also been studied. The method was simple, rapid and accurate. And the results could be directly used to determine CFCs in the refrigerant.
