We have investigated (i) the effect of preferential solvation on vapor-pressure osmometry results in mixed solvents close to theta-conditions and (ii) the danger of formation of associates by coarse-grained computer simulations. The study shows that both effects are negligible and the measurements in mixed solvents can be safely performed.
