A study in Food Science & Nutrition evaluated the antioxidant and preservative effects of Epilobium angustifolium extract on beef burgers, finding that the extract influenced physicochemical properties, color stability, and lipid oxidation, with higher concentrations showing a prooxidant effect.

Interest in applying artificial intelligence (AI) and machine learning (ML) to chromatography is greater than ever. In this article, we discuss data-related barriers to accomplishing this goal and how rethinking chromatography data systems can overcome them.

Joel Fabregat-Palau, a postdoctoral researcher at the University of Tübingen (Germany) discusses his latest research investigating per- and polyfluoroalkyl substances (PFAS) in agricultural soils using a targeted approach with high performance liquid chromatography tandem mass spectrometry (HPLC–MS/MS) and a non-targeted high performance liquid chromatography quadrupole time-of-flight mass spectrometry (HPLC–QTOF-MS) for semi-quantification.

Iowa State University researchers evaluated imidazolium-based ZILs with sulfonate and triflimide anions to understand the influence of ZILs’ chemical structures on polar analyte separation.
