The analysis of complex fossil fuel mixtures is usually done by capillary gas chromatography-mass spectrometry (GC-MS). Routine GC-MS cannot readily distinguish the isomers of many compounds. Infrared spectrometry can distinguish isomers, and can identify specific isomers even when they coelute. Gas chromatography-matrix isolation infrared spectroscopy (GC-MIIR) yields spectra that have sharper absorptions than those generated by other techniques. GC-MIIR also has lower detection limits than do other GC-IR techniques. In this study, C2 naphthalenes are examined by GC-MIIR. It is found that this family of compounds in complex fossil fuel mixtures cannot be differentiated by GC-MS but can be identified by GC-MIIR. |
