Combined DLS/Raman provides New Molecular Insights of Complex Fluids

| Sponsored by Malvern Panalytical

In particular, this article demonstrates the correlation between molecular changes (Raman Spectroscopy) and microstructural evolution of rheological properties (DLS, DLS-optical microrheology) for the first time for surfactant-based wormlike micellar system. Whereby, Raman Spectroscopy provides information about the molecular structure and DLS-microrheology characterizes viscoelastic properties, the combination of data delivered allows for a deeper understanding of the molecular changes underlying the viscoelastic ones. The study illustrates the utility of the combined DLS, DLS-optical microrheology and Raman Spectroscopy in providing new molecular structural insights into the self-assembly process in complex fluids.

Why should I upgrade to multi-detection GPC?

| Sponsored by Malvern Panalytical

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.

Characterizing method for polymers

| Sponsored by Malvern Panalytical

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.
