By using the small-angle X-ray scattering method, it is possible to evaluate the size distribution of powders, microparticles dispersed in liquid, and particles/pores distributed in thin films. In particular, it is possible to evaluate the average size and distribution of sub-nanometer particles, which are difficult to evaluate with a TEM (Transmission Electron Microscope) or DLS (Dynamic Light Scattering). In this case, we evaluated the size distribution of gold nanoparticles dispersed in organic solvent.
