Regulation EC 1883/2006 and EPA 1613 B	Regulation EC 1883/2006, ASU L 00.00–12 and ASU L 00.00–38	Proprietary method and EPA 1614	Proprietary method	Regulation ASU L 00209,.00–12, ASU L 00.00–38 Proprietary method (based on S19 multimethod)
High resolution GC/MS	High resolution GC/MS	High resolution HRGC/HRMS. To minimise the degradation of BDE 209, a short column (15 cm) was used (Agilent DB-5 ms 15 m × 0.25 mm × 0.25 µm) instead of the 30 cm column that were used for the other congeners	Using LC/MS–MS A daily internal lab blank was used as the QA/QC. the lab blanks were routinely analysed (once a week)	High resolution GC/MS
