A standardized methodology for the correction of scattering patterns, the calculation of uncertainties, the subtraction of backgrounds and solvents, optionally followed by the azimuthal averaging/reduction step, is presented.
22 laboratories returned 45 small-angle scattering datasets on a suspension of silver nanoparticles. The variance of the results has been analyzed in order to estimate the expected accuracy and precision of the small-angle scattering technique.
