Particle Diameter Distribution of Subnano Gold Particles using the Small-Angle X-ray Scattering Method

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 or DLS. In this application note, the size distribution of gold nanoparticles in organic solvent was evaluated.
