Particle size analysis-Dynamic light scattering(DLS)

This standard specifies the use of dynamic light scattering (DLS) measurements dispersed in a liquid submicron - nanoscale particles or droplets of an average particle size and particle size distribution approach. This standard applies to a wide range of concentrations, measurable from a lower to a higher concentration of suspension. For samples of low concentration suspensions, dynamic light scattering method with photon correlation spectroscopy as a suspension for the high concentration samples, in addition to the correct interpretation of the test results outside, but also on the measuring device, sample preparation and other specific requirements.
