摘　　要：用气相色谱以程序升温方式分析了蒸馏常顶汽油，并将各组分程序升温保留时间转换为恒温保留指数．以各组分在 ＯＶ－１和 ＳＥ－５４固定相上、同一柱温下的保留指数差及在各柱上的温度系数为三因素进行斜交因子分析，给出了蒸馏常顶汽油样品的ＰＯＮＡ值，经色谱－质谱仪分析验证了结果的正确性，为蒸馏常顶汽油样品的ＰＯＮＡ分析提供了一种新方法．A new method is proposed for the PONA analysis of gasoline with gas chromatography under programming temperature condition. The programming temperature retention time of each component of a straight run gasoline was transformed to constant temperature retention index. The difference between the retention indices of the components on stationary phases of OV- 1 and SE- 54 at the same temperature and their temperature coefficients on each column were processed with Promax oblique rotation. The PONA value of the straight run gasoline was obtained. The correctness of this method was proved by gas chromatography-mass spectrometry.
