Researchers in Italy Developed New GC-MS and LC-MS Analytical Methods for the Determination of Ink Photoinitiators in Packaged Beverages

A recent study used ultrahigh-pressure liquid chromatography (UHPLC) to identify traces of drugs on smartphones.

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.

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

Scientists from Anhui University of Chinese Medicine in Hefei, China recently investigated the mechanisms behind what makes huachansu tablets, a type of traditional Chinese medicine (TCM), effective against liver cancer.

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.

In this interview to commemorate Earth Day, Ana Torres-Agullo and Silvia Lacorte share the results of using Pyr-GC-Orbitrap-MS to simultaneously determine the presence of 10 polymers in the air.
