Instrument Capabilities

The dynamic Light Scattering (DLS) is used to determines the size distribution of particles in solution, emulsion, or suspension in a non-invasive or non-destructive method. In addition, the DLS also determines surface zeta potential of materials and the molecular weight (when coupled with a SEC system).

Key features

• DLS Detection: Colloid size and distribution measurements for particles from 0.3 nm to 9 microns in a minimum volume of 12 microliters.
• Zeta Potential: For zeta potential measurements, the particle size suitable for measurements is from 3.8 nm to ~10 microns in a minimum volume of 150 microliters.
• Accessories: include an MPT-2 auto titrator for measuring zeta potential as a function of pH, conductivity, or concentration of an additive.

Fees and Policies
