该气相色谱法用于测定最大终沸点为260°C、质量百分比小于2%烯烃（见注1）的碳氢化合物中的C8和低沸点石蜡和环烷烃。还测定了苯和甲苯。某些感兴趣的非芳香族成分被报告为复合物，C8芳香族化合物未被确定（见注2）。任何报告成分的定量限为0.01质量-%。

This gas chromatographic method is for determining C8 and lower boiling paraffins and naphthenes in hydrocarbons containing less than 2 mass-% olefins (see Note 1) having a maximum final boiling point of 260°C. Benzene and toluene are also determined. Certain non-aromatic components of interest are reported as composites and C8 aromatics are not determined (see Note 2). The quantitation limit for any reported component is 0.01 mass-%.
