Mass Spectrometry of Fatty Acids Derivatives
Unless otherwise stated, these pages were written by Dr. William W. Christie and deal with the application of mass spectrometry with electron-impact ionization to determine the structures of fatty acids in the form of various derivatives. If you are new to the subject, you may wish to first consult -
- A beginner's guide to mass spectrometry of fatty acids: Part 1
- A beginner's guide to mass spectrometry of fatty acids: Part 2
Further articles on mass spectrometry are available in the Lipidomics and Selected Topics in Analysis sections of this web site. PDF files can be downloaded from a link at the end of documents to give you an instantly accessible or printable record.
