Dynamic Light Scattering (DLS)
Malvern ZEN 3600 Zetasizer
Model: Malvern ZEN 3600 Zetasizer
Location: 014 Brauer Hall
Description: DLS sometimes referred to as Quasi Elastic Light Scattering (QELS), is a non-invasive, well-established technique for measuring the size, size distribution and zeta potential of molecules and particles typically in the submicron region.
- Accurate, reliable and repeatable particle size analysis in one or two minutes.
- Multi-Angle Dynamic Light Scattering (MADLS®) improves the resolution of DLS and provides angular independent size results.
- Simple, material independent measurement of per peak particle concentration.
- Mean size only requires knowledge of the viscosity of the liquid.
- Size measurement of sizes from <5nm to >10um
- Size measurement of molecules from MW < 1000Da.
- Low volume requirement (as little as 40µL).
- Characterization of particles, emulsions or molecules, which have been dispersed or dissolved in a liquid such as proteins, polymers, micelles, carbohydrates, nanoparticles, colloidal dispersions, emulsion, biological cell, gels and ions.
- Stability study by measurements of a sample can show whether the particles aggregate over time by seeing whether the hydrodynamic radius of the particle increases.
