DLS Dynamic Light Scattering Particle Size Analyzer
Dynamic light scattering particle size analyzer, abbreviated as DLS, uses laser light to illuminate a solution containing particles to be measured, causing the particles to scatter light.
Using the correlation function to process the intensity variation of scattered light caused by particle Brownian motion, the diffusion coefficient of the particles to be measured can be further obtained; finally, the hydrodynamic diameter can be calculated according to the Stokes-Einstein formula.
