Triple-quad GC/MS/MS method facilitates trace-level screening of PCDD/Fs and PCBs

Newly launched triple quadrupole gas chromatography tandem mass spectrometry (GC/MS/MS) instrument can reliably analyze PCDD/Fs and PCBs in foodstuff at the maximum residue levels (MRLs). A new method has been developed with the instrument for the trace-level screening of polychlorinated dioxins/furans (PCDD/Fs) and polychlorinated biphenyls (PCBs) in food products, following the analytical strategy of the well established US Environmental Protection Agency (EPA) Method 1613A.

The method, which incorporates the triple quadrupole GC-MS/MS with one of the manufacturer’s gas chromatographs, enables regulatory compliance for the trace-level screening and quantitation of PCDD/Fs and PCBs in foodstuffs. Using highly selective precursor ion selection and high-precision hyperbolic quadrupole technology, uniform selectivity for screening for PCDD/Fs and PCBs at imposed MRLs in complex matrices is possible.
