Abstract
Abstract An application of fast atom bombardment (FAB) for identification of some organic micro-pollutants was performed. A study of the most common surfactants, including non-ionic, cationic and anionic compounds was carried out and the results obtained used to build a table for rapid characterization of surfactants in real samples. Negative FAB and tandem mass spectrometry (CID-MIKE) were also occasionally employed, when two or more compounds gave the same series of peaks. Sensitivity limits for standards varied from low to upper nanogram range for cationic to anionic surfactants. Raw and drinking water extracts of Barcelona (N.E. Spain) were analysed and the most common surfactants and some brominated derivatives were identified.
