DLS Particle Size Distribution

Determination of particle size and distribution via Zetasizer Nano ZSP

The Malvern Nanosizer ZSP instrument can measure Zeta Potential as well as Dynamic Light Scattering. Dynamic light scattering (DLS), sometimes referred to as Quasi Elastic Light Scattering (QELS), is a non-invasive, well-established technique for measuring the size and size distribution of molecules and particles typically in the submicron region down to 10 nm.
