Multi-angle light-scattering data analysi

Figure 12 illustrates an example of direct molar mass measurement by lightscattering in a G PC experiment for a poly(vinyl butyral) sample. For each analytical fraction (elution volume slice), the LS detector determines the correct and subsequently the molar mass distribution can be determined without any further assumptions. Obviously, this sample contains species of very different molar mass and structure, as can be further elucidated by molecular size measurement, which is possible from the multi-angle light-scattering data analysis (cf Fig. 13).
