Collisionally-induced fragmentation of chlorinated n-paraffins
- Fisheries and Oceans, Winnipeg (Canada)
Chlorinated n-paraffins (CPs) are used as fire retardants, plasticisers in PVC, adhesives, and as extreme pressure additives in lubricants and cutting oils. They have also found use as replacement chemicals for more toxic and persistent chemicals such as PCBs. There have been a few reports of the mass spectrometric behavior of CPs. In these studies, efforts were made to resolve commercial mixtures by capillary gas chromatography (gc) columns, prior to introduction into the ion source. Because of the inherent complexity of commercial mixtures, most peaks eluting off the gc-column contained multiple components, and thus mass spectra were not of individual congeners. Clearly then, there is a need for individual CP congeners. Methods of synthesizing individual CP congeners have already been developed in this laboratory. In addition, the positive electron ionization (EI) and the electron capture negative ion (ECNI) mass spectrometry of these synthesized CP congeners have been described. In this report, the authors describe the fragmentation behavior of two individual CP congeners by examining the results of a detailed study of metastable and collisionally induced dissociation (CID, argon) processes. Fragmentation pathways were determined by B/E, B{sup 2}/E and CNL linked-field scanning.
