(Thermo Fisher Scientific: Waltham, MA) -- Thermo Fisher Scientific Inc., a world leader in serving science, has announced a new method 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 U.S. Environmental Protection Agency (EPA) Method 1613A.

The newly launched Thermo Scientific TSQ Quantum XLS 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.

The new method is described in an application note, entitled “PCDD/F Screening at the Maximum Residue Level for Food Safety Analysis Using Highly Selective Triple Quadrupole GC/MS/MS,” which is available for download via www.thermoscientific.com/pcdd.
