| Resumen: | This International Standard specifies a method for the determination of selected polybrominated diphenylethers (PBDE) (Table 1) in sediment and sludge using gas chromatography/mass spectrometry (GC-MS) in the electron impact (EI) or negative ion chemical ionisation (NCI) mode. When using GC-EI-MS, the method is applicable to samples containing 0,05 µg/kg to 25 µg/kg of tetra- to octabromo congeners and 0,3 µg/kg to 100 µg/kg of decabromo diphenyl ether (BDE 209), respectively. Approximately ten times lower concentrations can be quantified when using GC-NCI-MS. The risk of misinterpretation of interfering substances is smaller with EI due to its higher specifity. It is also possible to analyse other brominated diphenyl ethers according to this International Standard, after verifying its applicability in each case. |
