Mass Spectrometry of Fatty Acid Derivatives



These pages deal with the application of mass spectrometry (MS) with electron-impact ionization and linked to gas chromatography (GC) to determine the structures of fatty acids. Although methyl esters are used almost universally for GC separations and often for MS, they afford limited structural information only. On the other hand, certain nitrogen-containing derivatives, especially pyrrolidides, 4,4-dimethyloxazoline (DMOX) derivatives and 3-pyridylcarbinol ('picolinyl') esters, give much more specific data as discussed in the attached web pages, in which more than 735 mass spectra are illustrated (not counting the Archive sections with these and a further 1350 spectra). Spectra of some selected other lipids are also discussed. These web pages are updated regularly as new information becomes available.
