As a result, the technology reliably achieves reproducible measurement results at higher sample concentrations and shorter measurement times with improved accuracy. In this historical review, we discuss the basic principle, data analysis, and important precautions to be taken while analyzing colloids using DLS. A dynamic light scattering instrument (DLS Zetasizer Ultra, Malvern Panalytical) is useful for analysis of particles in solution, including nanoparticles. By separating the light of the p- and s-polarised laser beams via polarisation filters, a high signal-to-noise ratio is realised. Dynamic light scattering (DLS) has evolved as a fast, convenient tool for particle size analysis of noninteracting spherical colloids. The term dynamic refers therefore not to the sample movement as a whole, but instead to. or molecules causes laser light to be scattered at different intensities. ![]() The measuring principle is based on two separate laser beams polarised perpendicular to each other, which are directed into the measuring zone and returned parallel through the cuvette via the optics by a backscatter of 176°. With dynamic light scattering the sample suspension is usually at rest. Dynamic Light Scattering or DLS measures particle size and size distribution.
