Introduction:

　　Polybrominated diphenyl ethers(PBDEs)are among the most important and widely used flame retardants in a variety of different industrial products.They are found worldwide in matrices,moving them into the foucus of recent legislation banning 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.

　　Instruments

　　Thermo Scientific TRACE GC Ultra

　　Thermo Scientific TriPlus autosampler

　　Conclusions

　　Using the DFS high resolution GC/MS,polybrominated diphenyl ethers(PBDE)can be analyzed with highest selectivity providing LOQs in the low femtogram range.
