Light Scattering Techniques: Dynamic Light Scattering (DLS)/Static Light Scattering (SLS)/Electrophoretic Light Scattering (ELS)/Low Angle Laser Light Scattering (LALLS)

Equipment: Zetasizer Nano

Working Principle

  • Dilute particle motion is measured by laser light
  • The speed of the particle motion is inverse to the size of the particles

Technical Information

  • Particle size distribution from 10 µm to a few nm
  • Hydrodynamic particle diameter
  • Analysis of agglomerates in colloidal sample
  • Trace detection of agglomerates
  • Particle Zeta potential
  • Flocculation
  • Quality control tool for food analysis
