建立了一种相对快速的煤烟样品中多环芳烃（p.c.a.h）的鉴别和测定方法。单个碳氢化合物是由程序温度气相色谱法测定，使用双火焰电离检测器。通过与纯碳氢化合物的相对保留时间的比较和气相色谱分离的馏分的紫外吸收分光光度法确定气相色谱中的峰。描述了一种简单的收集这些分数并确保探测器灵敏度保持恒定的方法。正常和Hi-Pak填充柱均已采用。以乙烯和乙烷扩散火焰的烟尘分析为例。
A relatively rapid method of identifying and determining polycyclic aromatic hydrocarbons (p.c.a.h.) in soot samples has been developed. The individual hydrocarbons are determined by programmed temperature gas chromatography using dual flame ionization detectors. Peaks in the gas chromatogram are identified by comparing the relative retention times with those of pure hydrocarbons and by ultraviolet absorption spectrophotometry of the fractions separated by gas chromatography. A simple method of collecting these fractions and of ensuring that the detector sensitivity remains constant is described. Both normal and Hi-Pak packed columns have been employed. The analyses of soots from ethylene and ethane diffusion flames are given as examples.
