They used liquid and gas chromatography to fractionate the sample into its molecular constituents ; an electron beam then fragmented the separated molecules in a mass spectrometer to produce a spectrum indicating the basic chemical components 他们运用液相与气相层析法,将样本的组成分子分开,然后导入质谱分析仪,以电子束使已分离的分子断裂,进而产生出可识别基本化学组成的图谱。
