VecDec4SAS program for analyzing the dynamic processes observed by the small-angle scattering technique
A VecDec4SAS program has been developed to provide a fast and easy description of the dynamics of any process occurring in a nanoparticle solution observed by the small-angle scattering technique. The process should be characterized by the some conditional initial and final stages, in fractions of which all intermediate data are expanded. The program makes it possible to estimate the adequacy of two-basis approximation and indicate the presence of an additional process introducing a systematic error into the initial data. Scattering curves for human serum albumin protein in solutions with pH 7.4 and 3.0 and a concentration of 20 mg/mL, obtained on the DICSY station at the National Research Centre “Kurchatov Institute” in the solution temperature range from 25 to 70°C, were taken to be initial data to illustrate the potential of the program.
