Abstract：

　　As a result analysis of PBDEs have received increased interest due to their known toxicity. Similar to dioxins/furans and PCB's (polychlorinated biphenyls) polybrominated diphenyl ethers exist in a higher number of congeners (209) .

　　The most efficient analysis technique by far for these three application areas is high resolution GC/MS using isotope dilution technique for quantitation with highest precision and significance.

　　Instrument：

Thermo Scientific DFS high resolution GC/MS

Thermo Scientific TRACE GC Ultra™ gaschromatograph

　　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. The same analytical significance required in the analysis of dioxins and PCBs proved to be feasible for PBDEs as well. For further information please visit our website www.thermo.com/dfs.
