Technical Specification
  • Accurate, reliable and repeatable particle size analysis in one or two minutes.
  • Measurement in the native environment of the material.
  • Mean size only requires knowledge of the viscosity of the liquid.
  • Simple or no sample preparation, high concentration, turbid samples can be measured.
  • Simple set up and fully automated measurement.
  • Size measurement of sizes < 1nm
  • Size measurement of molecules with MW < 1000Da
  • Low volume requirement (as little as 121L)
  • Temperature dependent measurement range : 4 deg-90 deg
Applications of Dynamic Light Scattering

Typical applications of Dynamic Light Scattering are the measurement of the size and size distribution of particles emulsions and molecules dispersed or dissolved in a liquid. e.g.: Proteins, polymers, micelles, carbohydrates, nanoparticles, colloidal dispersions, emulsions, ions.
