DLS-803 dynamic light scattering nanometer particle size analyzer which based on the dynamic light scattering principle, Brownian motion principle. It adopts great performance of Japan HAMAMATSU photomultiplier and self-developed high speed digital correlator as core parts, get diffusion coefficient by test scattering light change in some angles, and calculate particle diameter and distribution according to stokes-Einstein equation. The analyzer is with characters of fast calculation, high resolution ration, good accuracy, and repeatability, it’s widely used in company product lab research and university, especially for testing particle size distribution of colored particles.
Be used for fields like metallic oxide, metallic powder, ceramic material, protein, polymer latex, preparation of pharmaceutical, water/oil emulsion, paint, coating material, pigment, ink, toner, cosmetics and other fields of research, preparation, and application of nano materials.
