🚨 PFAS Desorption (Short-Chain PFBA / PFBS Rollover by Long-Chain PFOA/PFOS)

PFAS Chromatographic Rollover Calculator

Model competitive chromatographic adsorption displacement (rollover) where long-chain PFAS compounds (PFOA, PFOS) desorb weakly-adsorbed short-chain perfluoroalkyl acids (PFBA, PFBS, GenX), causing effluent concentrations to spike above raw influent levels: optimize lead vessel carbon changeout intervals, and water compliance yields.
