摘要
气相色谱/付里叶变换红外光谱联机(GC/FTIR)是一种较新的分析技术,与气相色谱/质谱联机(GC/MS)具有互补性,特别适合于分离和鉴定复杂的芳香烃混合物。化石燃料中芳香混合物的GC/FTIR初步检测显示,该联用技术能较好地分离鉴定芳烃馏分中三甲基菲(TMP)和二甲萘(DMN)等几何异构体。实践表明,GC/FTIR在有机地球化学研究中具有广阔的应用前景,尤其是对于挖掘化石燃料中芳香化合物所蕴藏的丰富地球化学意义有着不可替代的作用。
Gas chromatography/Fourier transfrom infrared spectroscopy (GC/FTIR) is a relatively new analytical technique.The combined technique is especially suitable to separating and identifying complox aromatic mixtures,so,it can compensate the detection defect of gas chromatography/mass spectrometry (GC/MS) in this filed.Preliminary detection of aromatic mixtures in fossel fuel by GC/FTIR shows that is can identify the isomers of trimethylphenanthrene (TMP) and dimethylnaphthalene (DMN) more effectively. Up to now,it is proven that GC/FTIR has very extensive application in organic geochemistry,and especially,can be used to get a huge amount of geochemical information from aromatic compounds in fossel fuel.
