Abstract: The constituent analysis of fatty acid methyl esters in biodiesel at different GC-MS conditions was studied. A reasonable GC-MS condition, which is PEG-20M as GC column, constant 150℃ of column temperature, and 0.2 μL of injection volume, was selected. The ten main fatty acid methyl esters in biodiesel were commendably separated and identified. The test time was only 12 min. This method can be used for GC-MS constituent analysis of fatty acid methyl esters in different biodiesels made from different vegetable oils.

Key words: biodiesel, fatty acid methyl ester, GC-MS, analytical condition
