✦ Synopsis

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.
