Pressurized Liquid Extraction of Amines in Meat

The serum/plasma estradiol is useful for diagnosis, pathology, and therapeutic efficacy monitoring of estrogen-dependent diseases, according to the authors.

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.

On the occasion of Earth Day, University of Wisconsin-Madison graduate student and chemist Katelyn Michael speaks with LCGC about the methods she has been using to attempt to degrade known PFAS.

Here are the top five articles that the editors of LCGC International published this week.

A recent study from the University of Lyon demonstrated how mass spectrometry techniques, when coupled to data-independent acquisition (DIA), can advance omics research.

Scientists from the Netherlands created a new LC–MS/MS assay to test new small molecular inhibitors (SMIs) and their effectiveness in prognosing lung cancer.
