Fossil fuel characterization using laser desorption mass spectrometry: Applications and limitations
- Argonne National Lab., IL (United States)
High molecular weight compounds (>600 amu) in fossil fuels have been overlooked in the past principally because of inappropriate analytical techniques. Most of the techniques have accessed only the easily volatilizable fraction. Mass spectrometry characterization of any presumed heavy components has mostly depended on pyrolysis to break up the larger molecules prior to analysis, especially by pyrolysis gas chromatography mass spectrometry. The material that is outside of the volatilizable fractions has received little attention. However, laser desorption mass spectrometry (LDMS) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI) are particularly applicable to those molecules which resist intact ionization by traditional gas-phase methods. The application and limitations of these techniques to model compounds and fossil-derived materials is discussed in this study.
