  • The method is accredited with a flexible scope for all matrices and analytes listed below

Number of samples

  • Also for single samples


  • Serum, breast milk, placenta and other human samples
  • Fish and other animal samples
  • Food and feed
  • Soil, sediment and other environmental samples suitable for routine analysis
  • Water
  • Other samples containing fat or oil

Method description

  • After matrix-specific pretreatment, analytes are extracted and the extract is cleaned with a silica and aluminium oxide column. The analytes are separated with an active carbon column. The quantification is performed with a gas chromatograph coupled to a triple quadrupole mass spectrometer (GC-MS/MS).

Limit of quantification

  • Depends on the sample amount and matrix
  • For example PBDEs in tissues: 10–100 pg/g fat

Sampling instructions

  • Sample container: glass, polyethene (PE) or aluminium foil
  • Avoid contact with plastics
  • Minimum sample amount: liquids 1000 ml, serum and breast milk 100 ml, soil and sediment 50 g, food and feed 1000 g (EU N:o 252/2012), fat 10 g
  • Maximum storage time (water, soil and sediment): +7°C for 7 days, -18°C for at least 20 years, -70°C or in liquid nitrogen indefinitely
  • Maximum storage time (other samples): +7°C for 3 days, -18°C for at least 20 years, -70°C or in liquid nitrogen indefinitely
