Molecular mass distribution of solubilized material. (A,B) High performance size exclusion chromatography (HPSEC) elution pattern of 0-0 (black), 120-1 (light grey), 140-1 (grey) and 170-1 (dark grey).(A) Solid lines = RI signal, (B) dashed lines = UV signal at 325 nm. (C) Logarithm of the combined severity factor (log R'0) vs. the relative RI peak area. Black triangles = peak area of the time interval 7.0 to 11.0 minutes, grey triangles = peak area of the time interval 11.0 to 13.0 minutes, white triangles = peak area of the time interval 13.0 to 15.2 minutes. Lines show trends.
