- W3211441485 abstract "The recent establishment of maximum residue limits for polychlorodibenzo-pdioxins (PCDDs) and dibenzofurans (PCDFs) in food and feed samples by the European Community and the future inclusion of dioxin-like polychlorinated biphenyls (dl-PCBs) in these values at the end of 2006, has led to an important increase on the routine analysis of these compounds. Therefore, there is a clear need to have powerful sensitive and selective methods for the analysis of these compounds at low concentration levels. Actually, gas chromatography coupled with high resolution mass spectrometry (GC-HRMS) is the technique of reference for the determination of these analytes in environmental and food samples due to its high sensitivity and selectivity. Nevertheless, this technique is relatively expensive and requires qualifier personnel. Therefore, the development of more economical but reliable methods that can deliver results comparable to GC-HRMS is required. During the last years, gas chromatography coupled with ion trap mass spectrometry (GC-ITMS) working in MS/MS mode has become an interesting alternative technique to GC-HRMS for the analysis of PCDD/Fs and dl-PCBs. The aim of the present work is to demonstrate the ability of the gas chromatography coupled with ion-trap tandem mass spectrometry (GC-ITMS/MS) for the analysis of PCDD/Fs and dl-PCBs in food and feed samples. This work was performed on the framework of the European research project called DIFFERENCE (Dioxins in Food and Feed - Reference methods and New Certified Reference Materials) with the objective to validate the GC-ITMS/MS method as alternative to HRMS in order to reduce the cost of dioxin analysis. The results and conclusions of the evaluation study are presented here." @default.
