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 >
