The Role of Ion Chromatography in Food Safety Laboratories

Researchers from the University of Mazandaran have developed a new system using HPLC-UV for extracting drugs using high-performance liquid chromatography-ultraviolet spectroscopy systems.

Food 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.

U.S. Department of Agriculture researchers used QuEChERSER-based methods to analyze chemical contaminants in foodstuffs in a new study published in the Journal of Chromatography A.

A new approach to characterizing human milk oligosaccharides was developed using a combination of liquid chromatography, mass spectrometry, and other techniques.

Scientists from the Zhejiang Institute of Quality Scientists used liquid chromatography–tandem mass spectrometry to detect 35 PFAS in paper and plastic products.

Cation exchange chromatography was tested for its effects on the elution behavior of the vesicular stomatitis virus, which is a contagious disease among livestock.
