The Application Notebook-07-01-2006

This application note will demonstrate a GC–MS analysis of common polybrominated diphenyl ether (PBDE) congeners. An optimized method will allow the Clarus GC–MS to provide ample separation and high yields of all PBDE congeners. The extended mass range of the Clarus 500 MS and high-mass calibration will produce mass spectra with very high levels of accuracy.

Polybrominated diphenyl ethers (PBDEs) are among the most important and widely used flame retardants. Recent legislation banned certain PBDE congeners.? EU directive 2003/11/EC prohibits the use of Penta-BDE and Octa-BDE for the member states of the European community.? Therefore, analysis of PBDEs have received increased interest as a result of their known toxicity.
