Metrohm's 2025 Young Chemist Explores Supercritical Water Oxidation in PFAS Research
March 6th 2025In this video interview from Pittcon, Elham "Elle" Akbari sat down with LCGC International to discuss her research, as well as the challenges of using liquid chromatography–mass spectrometry (LC–MS) and combustion ion chromatography (CIC) to characterize PFAS in environmental samples.
An LC–HRMS Method for Separation and Identification of Hemoglobin Variant Subunits
March 6th 2025Researchers from Stanford University’s School of Medicine and Stanford Health Care report the development of a liquid chromatography high-resolution mass spectrometry (LC–HRMS) method for identifying hemoglobin (Hb) variants. The method can effectively separate several pairs of normal and variant Hb subunits with mass shifts of less than 1 Da and accurately identify them in intact-protein and top-down analyses.
