Lignin derivatives sedimentation equilibrium

For the work with lignin derivatives in THF described here, the sedimentation equilibrium data were presented in terms of Rayleigh interference patterns using Equation (14). It was assumed that, at the 1-2 g/liter solute concentrations used, ideal behavior in THF would prevail and therefore the data were collected at one concentration only. It is not currently known, however, what would constitute theta conditions for lignin derivatives in THF.
