PCDD/F SCREENING AT THE MAXIMUM RESIDUE LEVEL FOR FOOD SAFETY ANALYSIS USING HIGHLY SELECTIVE TRIPLE QUADRUPOLE GC-MSMS
This paper presents a trace level screening method for PCDD/Fs and PCBs at the relevant maximum residue level for foodstuff. The method described employs a triple quadrupole mass spectrometer equipped with hyperbolic quadrupole rods for increased selectivity. The described MRM method is using selected MS/MS transitions for polychlorinated dioxins/furans and PCBs from two different precursor ions and detecting individual product ions for each chlorination degree. The analytical strategy follows the well-established United States Environmental Protection Agency (US EPA) Method 1613A by using isotope dilution quantitation with 13 C labeled internal standards.
