A preliminary investigation of silver ion interactions with saturated and unsaturated fatty acid methyl esters under liquid‐assisted secondary ion mass spectral conditions is reported. Collision induced dissociation studies of silver cationized species, [M + Ag] + , have shown regular charge remote fragmentation, characteristic of cationized species, in addition to series of ions, due to addition of Ag + to the double bond in the case of the unsaturated compounds studied. These results are further substantiated by deuterium labelling. © 1997 John Wiley & Sons, Ltd.
