METHOD FOR DETERMINING SIZES OF NANOPARTICLES ADDED TO INITIAL COLLOIDAL SOLUTION Russian patent published in 2017 - IPC G01N15/02 B82B1/00

Abstract RU 2630447 C1

FIELD: measuring equipment.

SUBSTANCE: method for determining the sizes of nanoparticles added to initial colloidal solution involves irradiating the solution with added nanoparticles by laser radiation. Measuring the current intensity of scattered radiation for a predetermined period of time and calculating the size distribution of nanoparticles in said solution I_irr(d) by the dynamic scattering method. Wherein the size distribution of nanoparticles in the initial solution I_ph(d) is preliminary obtained by a similar method, the average photon counting rate is measured for said period of time for the initial solution P_ph and the solution with added nanoparticles P_irr and the transmission coefficients at the wavelength of the laser radiation for the initial solution T_ph and the solution with added nanoparticles T_irrare measured. The size distribution of the added nanoparticles is calculated as .

EFFECT: simplifying determining the sizes of nanoparticles added to the initial colloidal solution.
