ISO 22032:2006 specifies a method for the determination of selected polybrominated diphenyl ethers (PBDE) in sediment and sludge using gas chromatography/mass spectrometry (GC-MS) in the electron impact (EI) or negative ion chemical ionization (NCI) mode. When using GC-EI-MS, the method is applicable to samples containing 0,05 to 25 micrograms per kilogram of tetra- to octabromo congeners and 0,3 to 100 micrograms per kilogram of decabromo diphenyl ether (BDE-209), respectively.
