Fig. 3. Comparison of the FI and LC AF4 methods. Fractograms obtained for LNP1-RNA by applying a linearly decreasing XF profile for Lab1 (black) and Lab 2 (red) using (A) the LC and (B) the FI channel. Light scattering intensity and UV–Vis absorption are reported on the left and right panels, respectively, together with the Rg profile estimated by Berry model. C) Summary of the results averaged over 3 measurements. Values in parentheses represent the standard deviation of the mean.
