适用范围：This International Standard specifies a method for the determination of selected polybrominated diphenylethers (PBDE) (see Figure 1 and Table 1) in sediment and sludge using gas chromatography/massspectrometry (GC-MS) in the electron impact (El) or negative ion chemical ionization (NCI) mode.When using GC-EI-MS, the method is applicable to samples containing 0,05 μg/kg to 25 μg/kg of tetra- tooctabromo 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 ofmisinterpretation of interfering substances is smaller with El due to its higher specificity. It is also possible to analyse other brominated diphenyl ethers according to this International Standard, after verifying itsapplicability in each case.
