Introduction:Particle size measurement of fine particles
5.Analysis principle of dynamic light scattering method
From the autocorrelation function obtained by the photon correlation method, the average particle size d (hydrodynamic diameter) and polydispersity index are obtained by the cumulant method, and the particle size distribution is obtained by the histogram method.
