A system consisting of a gas chromatograph coupled to a mass spectrometer and computer has been used to characterize the extractable acidic components of Green River shale. This system accumulates mass spectra at every point of the gas chromatogram in a permanent form which permits one to observe mass spectra of minor as well as major constituents. One minor component, whose identification was confirmed by synthesis, was 6,10,14-trimethyl-pentadecanoic acid.
已采用气相色谱仪-质谱仪-计算机联用系统来对绿河页岩中的可萃取酸性组分进行特征分析。该系统以永久形式在气相色谱的每一位置积累质谱图,从而可以观察到微量和主要组份的质谱图。一种经合成确证的微量组份是 6,10,14-三甲基十五烷酸。
