Orthogonal Chromatographic Techniques for the Quantitative Analysis of Potential Mutagenic Impurities

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.

David 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).

Cinnamon and its byproducts have been used for many years because of their antidiabetic effect. In a joint study conducted by Gazi University (Ankara, Turkey) and Düzce University (Düzce, Turkey), high performance liquid chromatographic (HPLC) and thin-layer chromatography (TLC) analyses, macroscopic analyses, and enzyme inhibition assays on diabetes-related enzymes were performed on cinnamon samples to determine whether they are safe to use for health purposes.

Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
