Abstract

The EU-report contains the method description for the determination of PCBs in food and feedingstuffs by using GC/MS. In addition, the results of the in-house validation are shown.

Principal of the method:
The homogenized sample is mixed with sodium sulphate, quartz sand and an internal standard (PCB congener No. 209) and transferred into a chromatographic column. The fat portion and the PCBs are extracted from the sample with a mixture of n-hexane and acetone and the liquid extract is evaporated to a defined volume. The extract is divided into two portions for the subsequent fat determination of the sample and the PCB-analysis. The PCB-analysis is comprised of two steps: (1) the de-fatting of the extract with concentrated sulphuric acid and (2) the quantification of the target PCBs congeners by GC/MS (selected ion monitoring).
