The intrinsic viscosity, is an important property in order to characterize macromolecules and nanoparticles. The evaluation of the intrinsic viscosity by single-point determination, like that based on the Solomon-Ciuta equation, is an efficient alternative to dilute solution procedures. However, single-point procedures have a bias respect to the value obtained by dilute procedures that depends on the strength of the concentration dependence of the solution viscosity (represented by the intrinsic viscosity and the Huggins constant) and the concentration of the single measured solution. The SCVISCOR program corrects the experimental value of the intrinsic viscosity obtained by the single-point Solomon-Ciuta method. For that purpose, the user must supply an estimate value for the system Huggins constant. The SIMULERROR program simulates a viscometric experiment and evaluates the systematic and global errors for different procedures: Huggins (dilute solution viscosimetry), single-point Solomon-Ciuta and corrected Solomon-Ciuta.
