Certification of Mass Fractions of Polychlorinated Biphenyls (PCBs 28, 52, 74, 99, 101, 105, 110, 118, 138, 149, 153, 156, 177, 180, 183, 187, 194 and 196) in Fish Oil - Certified Reference Material ERM®-BB350
This report describes the preparation of a salmon oil matrix certified reference material (ERM-BB350) and the certification of the content (mass fraction) of a selection of polychlorinated biphenyls (Nos. 28, 52, 74, 99, 101, 105, 110, 118, 138, 149, 153, 156, 177, 180, 183, 187, 194 and 196).
Certification of the CRM included testing of the homogeneity and stability of the material as well as the characterisation using an inter-comparison approach. The main purpose of the material is to assess method performance, i.e. for checking accuracy of analytical results. As any reference material, the CRM can also be used for control charts or validation studies.
Uncertainties were calculated in compliance with the Guide to the Expression of Uncertainty in Measurement (GUM) [1] and include uncertainties due to possible heterogeneity, instability and characterisation. The certified values for the mass fractions of PCBs are traceable to the SI
