Researchers at the Universit? di Camerino in Camerino, Italy have developed a new GC-MS and LC-MS technique for the determination of five ink photoinitiator residues: 2-isopropylthioxanthone (ITX), benzophenone, 2-ethylhexyl-4-dimethylaminobenzoate (EHDAB), 1-hydroxycyclohexyl-1-phenyl ketone (IRGACURE 184) and ethyl-4-dimethylaminobenzoate (EDAB) in packaged beverages.

The work proposes a new method to analyze ink photoinitiator residues in polycoupled carton packaging and in contained food beverages.
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.
Fundamentals of Benchtop GC–MS Data Analysis and Terminology
April 5th 2025In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.
Advances in Non-Targeted Analysis for PFAS in Environmental Matrices
March 27th 2025David Megson from Manchester Metropolitan University in Manchester, UK, spoke to LCGC International about the latest developments in non-targeted analysis (NTA) of per- and polyfluoroalkyl substances (PFAS) in environmental matrices based on a recent systematic review paper he has collaboratively published (1).
