Fragmentation of methylstearate has been examined by introducing a method for separation and classification of fragment ions into homologous series observed in high-resolution EI and FI mass spectra. The fragment ions were classified into three homologous series, i.e., aliphatic hydrocarbon, acylium and methylester. Original EI/FI mass spectra were reconstructed from the homologous series ions, and the formation of complementary fragment ions was analyzed on the basis of the reconstructed EI/FI mass spectra.
