Time to spec up? Replace a viscometer with a rheometer

|

Is your viscometer approaching the end of its life? Are you starting to feel that your trial and error, ‘rheology-light’ approach to formulation is becoming dated? Or are there longstanding product performance issues that you’re failing to gain traction with, where you suspect rheology may hold the answer?

Protein measurements with the Zetasizer µV

|

This application note describes a selection of measurements made on a GE AKTA basic system. Since the unit only contains a UV detector for measuring sample concentration, this can be used for the molecular weight calculations instead of the more commonly used refractive index detector, provided that the molar extinction coefficient of the sample protein is known. If this is not known, then reliable estimates can be made based on the amino acid sequence of the sample.

Performance of Polymer Solutions for Enhanced Oil Recovery

|

In this article we take an introductory look at work carried out by TU Clausthal to develop an improved understanding of the mechanisms of enhanced oil recovery (EOR) by polymer flooding, and the relevance of fluid rheology. Example data illustrates the insight that rheology provides and its application in optimizing fluid performance.

Combined DLS/Raman provides New Molecular Insights of Complex Fluids

|

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.
