Breaking Barriers: The Rise of Inert Column Technologies for Small Molecule HPLC

Metal-analyte interactions can derail even the most optimized HPLC methods, especially for compounds containing phosphates, carboxylates, or chelating groups. This session explores the evolution of surface deactivation technologies—specifically hybrid organic/inorganic coatings—and their ability to reduce peak tailing, improve analyte recovery, and enhance reproducibility.
See how new inert column solutions are reshaping workflows in pharmaceutical analysis and metabolomics.
