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.
