Nanofiltration membrane experiments with the mixtures of E1, E2, T, and P (100 ng/L each). (a) UHPLC-FSA radiochromatograms, (b) the normalised peak area for each analyte in feed, permeate and retentate samples. The permeate was collected after filtration of 700 mL volume. The error bar was estimated via error propagation approach as presented in Supplementary Information.
