Winner802 dynamic light scattering nanometer particle size analyzer which based on the dynamic light scattering principle, and also 1st one which use digital correlator in China. And Itâs upgrade from Winner801, which is 1st set of Nanometer particle size analyzer. Based on Brownian motion principle, smaller particle, faster speed, bigger particle, more slowly. It adopt great performance of Japan HAMAMATSU tomultiplier and self-developed high speed digital correlator as core parts, Get diffusion coefficient by test scattering light change in some angle, and calculate particle diameter and distribution according to stokes-Einstein equation. the machine is with characters of fast calculation, high resolution ration, good accuracy and repeatability, therefore itâs widely used in company product lab research and university use.
