The mass spectra of a series of saturated (C16:0-C30:0) and unsaturated (C16:1 C18:1 C18:2 C18:3) fatty acids have been recorded as their anilides using liquid chromatography/mass spectrometry with the atmospheric-pressure-ionization interface system. The spectra show an intense peak for (molecule+H)plus ion in each case. The liquid chromatographic/mass spectrometric separation was performed on a reverse phase column using a solvent system of methanol alone or methanol + 2-propanol. This method seemed promising for application to both qualitative and quantitative micro-analysis of fatty acids including very long chain fatty acids.
