A basic introduction to Dynamic Light Scattering (DLS) for particle size analysis – Q&A

Dynamic Light Scattering (DLS), sometimes referred to as Photon Correlation Spectroscopy or Quasi-Elastic Light Scattering, is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern…READ MORE >

Polydispersity – what does it mean for DLS and chromatography?

The term polydispersity (or more recently dispersity without the poly, as per IUPAC recommendation) is used to describe the degree of “non-uniformity” of a distribution.  In the field of molecular/nanoparticular characterization, there are in principle two different definitions of polydispersity,…READ MORE >
