10 reasons for polymer characterization scientists. Gel-permeation chromatography (GPC) is an essential tool for the characterization of polymers. It allows polymer scientists to tailor a polymer’s properties to its end use requirements by controlling its molecular properties, since the two are inextricably linked.

Nanoparticle Tracking Analysis (NTA) has found use in a variety of investigations researching the toxicity and environmental impact of nanoparticles. Here we discuss various publications in which NTA has been used to measure particle size and concentration of nanomaterials in waste water.

This whitepaper reviews the methods available for measuring the key characteristics of polymers focusing on the benefits and value of gel permeation / size exclusion chromatography (GPC/SEC). Much of the paper talks exclusively about polymers, however many of the principles discussed are equally applicable to proteins or protein conjugate materials.

This white paper offers practical guidance on using a range of analytical techniques, including rheology, particle size and zeta potential measurement to assist in the formulation of Inkjet inks.

The complementarities of two techniques, dynamic light scattering (DLS) and static light scattering detector coupled with a size exclusion chromatography system (SEC-LS), are illustrated by studying a number of samples where a thermally denatured and aggregated protein sample were dosed at different levels into a non-denatured protein sample.

In this application note, intrinsic viscosity measurements were performed on the sRAGE protein to establish whether the detector was able to detect and characterize the conformational change induced by the presence of calcium. Light scattering molecular weight measurements were also performed. Data are also presented showing that the conformation of sRAGE changes in the presence and absence of calcium.
