Rayleigh scattering particle size
WebA forward scattering angle of 13° is also available for particle size measurement. The Zetasizer can measure particle diameters in the range of 0.6 nm and 6 µm. Zeta Potential. … WebApr 27, 2024 · , which can be computed using different scattering theories. 2.1 Rayleigh theory If particle size is much less than light wavelength, all elementary dipoles of particle emit coherently. This case of scattering is named after Lord Rayleigh who determined the dependence of the intensity of scattered light on the wavelength in 1871.
