Equipment Description
Dynamic Light Scattering (DLS) is a solution-based analytical technique used to determine the hydrodynamic diameter and particle size distribution of particles dispersed in a solvent. The instrument can perform three types of measurements: particle size (from 0.6 nm to 6 µm), zeta potential, and the molar mass of polymers. Samples with analyte concentrations of up to 40% can be analyzed. The opacity and homogeneity of the sample may affect measurement accuracy.
