β¦ Synopsis
Organic compounds in raw and drinking water, not amenable to gas chromatogaphy/mass spectrometry, were characterized by fast atom bombardment (FAB) and collision-induced decomposition/mass-analysed ion kinetic energy (CID/MIKE) spectrometry. Anionic, cationic and non-ionic surfactants were successfully identified by comparison of their FAB spectrum and CID/MIKE of prominent ions with commercial standards. Organic dyes were spiked to water extracts and the detection limit for some of them reported.

In this paper, we have shown that it is possible to differentiate an aspartic acid residue from its p-aspartic acid isomer in dipeptides according to the characteristic fragmentation pathways, i.e. specific immonium ion formation and cleavages involving side-chain atoms.
