| Ketones in fossil fuel are a group of reactive compounds but have never been much studied. Gas chromatography (GC) and/or GC-mass spectrometry (GC-MS) is not applicable to the analysis of nonvolatile compounds, so chemical derivatization to selectively introduce a positive charge into ketones for MS detection is an alternative for universal profiling and trace analysis of ketones. Since positive ions are formed, the ESI-MS detectability is excellent. In order to be detectable at all, the derivatives must be separated from interfering nitrogen heterocycles, but this separation can be done through a simple and rapid chromatographic step to avoid complete suppression of the signals of the derivatives. |
