Mass fragmentation online
WebIn mass spectra of methyl esters of fatty acids of the n -3 family, the omega ion stands out at m/z = 108 (while that at m/z = 150 is negligible), and for the minor ( n -9) and ( n -4) biosynthetic families of fatty acids, the relevant ions are at m/z = 192 and 122, respectively. It should be stressed that these ions are valuable but not ...
