摘要
在运用GC/MS技术的基础上采用直观推导式演进特征投影法(HELP)对93号汽油进行了成分分析。采用面积归一化方法对各成分进行了相对定量。结果共检测出191个成分,其中准确定性定量的有139个物质,主要为链烷烃,环烷烃,烯烃,芳香烃。利用GC/MS结合化学计量学的分辨方法鉴定汽油成分,比单独使用GC/MS法结果更准确、可靠。
The components of gasoline 93^# was analyzed by GC - MS combined with the help of heuristic evolving latent projection （HELP） resolutions. Relative contents of each component were computed using the normalization method of peak area. As a result, 191 compounds were identified in which 139 components were accurately determined. The compounds were mainly paraffins, naphthenes, olefins and aromatics. Compared to simply using GC - MS, the results obtained by the analysis of GC - MS c, ombined with chemometric resolution method were more reliable and accurate.
