Concentrations of individual polychlorinated biphenyl congeners from Standard Reference Material (SRM) 1944

Five Standard Reference Material 1944, New York, New Jersey Waterway sediment (SRM 1944, National Institutes of Standards and Testing) were extracted, cleaned and quantified using the same method for soils. Gas chromatography (GC) in tandem with Mass Spectrometry GC-MS/MS (Agilent 7000) in multiple reaction monitoring (MRM) mode was used to quantify all 28 individual or coeluting certified congeners. The GC was equipped with a Supelco SBP-Octyl capillary column (30 m × 0.25 mm ID, 0.25 mm film thicknesses) with helium as carrier gas
