Dynamic Light Scattering (DLS)

Model:  Malvern Zetasizer Advance Pro

Location: 014 Brauer Hall

Description: Dynamic Light Scattering 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.

Capabilities:

• Accurate, reliable, and repeatable particle size analysis in one or two minutes.
• 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 20µL).

Typical uses:

• Characterization of particles, emulsions, or molecules, which have been dispersed or dissolved in a liquid such as proteins, polymers, micelles, carbohydrates, nanoparticles, colloidal dispersions, emulsions, biological cells, gels, and ions.
• A 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.
