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 >

What are Polyolefin Polymers? Polyolefins are macromolecules formed by the polymerization of olefin monomer units. The IUPAC nomenclature term is poly(alkene). The most common polyolefins are polypropylene (PP) and polyethylene (PE). These polymers are prevalent in a wide array of…READ MORE >

Multi-detector SEC – 10 reasons why protein scientists need one In a previous post I listed the top ten reasons why a polymer characterization scientist might want to upgrade to multi-detector Gel Permeation Chromatography/Size Exclusion Chromatography, but there are similar…READ MORE >
