AP-900 NANO Laser Particle Size Analyzer
Introduction
AP-900 dynamic light scattering nanometer particle size analyzer is based on the dynamic light scattering principle. It’s also the 1st one which uses digital correlator in China. 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 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, it’s widely used in company & university product labs.

Applications
Its application includes: Nano metallic oxide, Nano metallic powder, Nano 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 others.
