We have recently developed a methodology to obtain a quantitative description on protein solvation shell by a set of in-solution small angle scattering experiments, simultaneously analysed by a global-fit approach. In this paper, numerical simulations of small angle scattering curves are presented to figure out the sensitivity of the technique to different experimental conditions. Simulations concern two model proteins of different molecular weights and an unique cosolvent. A reliability test is introduced in order to find the best experimental conditions to be investigated, together with the most suitable scattering probe (neutrons or X-rays).
