Abstract. Particle size and zeta potential analyzers Photocor have been developed and are mass-produced by the Russian company Photocor. The principle of operation of the analyzers is based on the dynamic light scattering method. Photocor instruments have a certificate of type approval of measuring instruments and are included in the Russian Federal Information Fund for Ensuring the Uniformity of Measurements.

Keywords: dynamic light scattering, nanoparticle size, diffusion coefficient, correlation function, zeta potential.

Full texts of articles are available only in Russian in printed issues of the magazine.
