Static light scattering for determination of physical parameters of macro- and nanoparticles

摘要

The work is dedicated to determination of physical parameters of micro- and nanoparticles by static light scattering method. We present static light scattering device and theory to determine sizes of particles in suspensions. We analyze calculated distributions of scattering intensity for particles of different sizes and compare it with experimental data, received for spherical particles of different sizes. We also suggest theory to calculate form factor of scattering intensity for micro- and nanoparticles of different shapes. We also demonstrated that Rayleigh scattering theory is better to be applied for small particles investigation.
