Fig 2. Results of the SEC-TDA characterization of the water-soluble fraction of the gels.
(a) Overlap of the chromatographic profiles (RI signal): RL (circles); JV (triangles); TRH4 (×); ASV (squares). (b) Complete chromatographic report: weight average molar mass (Mw), numeric average molar mass (Mn), polydispersity index (Mw/Mn), intrinsic viscosity ([η]), hydrodynamic radius (Rh). For TRH4, the data resulting from the analysis of the two distributions are reported. The high molecular weight fraction represents the 53±1% w/w of the total soluble HA amount. (c) Overlap of representative Mark-Houwink-Sakurada curves for (on the left) a linear HA control (stars), RL (circles), JV (triangles), TRH4 II distribution (×) and ASV (squares) and for (on the right) a linear HA control (empty and filled squares) and TRH4 I distribution (×).
