Abstract
In recent years ionisation by Fast Atom Bombardment (FAB) has been developed to enable mass spectrometric (MS) analysis to be performed on samples containing polar, involatile compounds without any pre-derivatisation. This makes FAB MS an ideal candidate for the analysis of polar petrochemical waste products. In addition, the soft ionisation induced by FAB minimises fragmentation, enabling complex mixtures to be screened routinely without lengthy sample work-up. Confirmatory identification of components can be obtained at high MS resolution. The present study reports the use of FAB MS to monitor specific petrochemicals in the aqueous effluents from certain coastal plants.
