This application note describes two retention time locked methods and retention time databases that improve the analysis of fatty acid methyl esters. In the first method, fatty acid methyl esters are analyzed on a DB-Wax column using gas chromatography/flame ionization detector or gas chromatography/mass spectrometry. In the second method, a DB-23 column is used. Retention time and mass spectral libraries are available for both methods. Retention time locking allows easy peak identification, easy exchange of data between instruments (gas chromatography/flame ionization detector, gas chromatography/mass spectrometry, different labs), and avoids the need to modify the retention times in calibra- tion tables after column maintenance or column change.
