Chiral Analysis of Flavours and Fragrances: Design of a FID/MS Splitting for MS Detection in The First and Second Dimension of a Multidimensional GC–MS System
Design of a FID/MS Splitting for MS Detection in The First and Second Dimension of a Multidimensional GC–MS System
Food, flavour and fragrance products are known to be complex mixtures. Analyses of these products are performed to determine their composition, control their quality and to identify adulterations or product counterfeiting. In this respect, proper characterizations of the enantiomeric composition can provide information on the genuineness, geographic origin, biogenesis and quality of the product.
Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
Analysis of Pesticides in Foods Using GC–MS/MS: An Interview with José Fernando Huertas-Pérez
December 16th 2024In this LCGC International interview with José Fernando Huertas-Pérez who is a specialist in chemical contaminants analytics and mitigation at the Nestlé Institute for Food Safety and Analytical Sciences at Nestlé Research in Switzerland, In this interview we discuss his recent research work published in Food Chemistry on the subject of a method for quantifying multi-residue pesticides in food matrices using gas chromatography–tandem mass spectrometry (GC–MS/MS) (1).
