Practical Considerations of the Influence of Organic Modifiers on the Ionization of Analytes and Buffers in Reversed-Phase LC

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.

Using pyrolysis-gas chromatography and mass spectrometry, scientists from Fudan University and the Putuo District Center for Disease Control and Prevention detected and quantified microplastics in newborn stool samples.

A study conducted at Henan University of Science and Technology (Luoyang, China).aimed to characterize the pharmacokinetic profiles of milbemycin oxime in Pekingese dogs following a single oral (PO) and intravenous (IV) dose. Blood samples were collected at various time points, with milbemycin oxime concentrations measured using a validated high performance liquid chromatography (HPLC) method with ultraviolet (UV) detection.

Emanuela Gionfriddo and Madison Williams from University at Buffalo, the State University of New York, NY, USA discuss the important role that solid-phase microextraction (SPME) techniques with gas chromatography mass spectrometry (GC–MS) can play in the analysis of per- and polyfluoroalkyl substances (PFAS).
