气相色谱法聚合级丙烯中烃类杂质的测定

Gas Chromatography Determination of Hydrocarbon Impurities in Propylene

用优化后的色谱分析条件分析工业用高纯度丙烯中烃类杂质,采用与标准气对照保留时间进行定性,用峰面积归一化法进行定量。此法一次进样,能较好分离含多组分的烃类杂质,并与原扬州石化标准相比该法具有操作简单、速度快、准确度高、重复性好、检测灵敏度高等特点。

Organic impurities in high purity industrial propylene were analyzed under optinized chromatographic con- ditions. The impurities were qualitatively determined by contrasting with standard sample （ standard gas） and quantitatively determined by area normalization method. This analysis method can accurately separate muhicomponent hydrocarbon im- purities. Compared to original Yang Petrochemical standard, this method had the characteristics of easy operation, fast speed, high accuracy, good repeatability and high sensitivity.
