Elevate your mineral analysis for greater production savings

The heavy cost of mining and minerals manufacturing
The importance of minerals as a production resource applies to many facets of our daily lives. For instance, the quality of concrete determines the smoothness of a road surface and the sturdiness of a building. However, with the ever-growing demands for quality cement, many have spurred manufacturing processes leading to hefty costs. Such costs incurred comes from wastage when having to reproduce cement because it does not meet the quality standard.
Based on a mechanical and civil engineering study, 6-15% of construction costs …

Beyond the Malvern Panalytical stand at Powtech

I have just come back from presenting my talk ‘Application of Morphologically-Directed Raman Spectroscopy in deformulation and in vitro bioequivalence studies’ at the pharma focus session of Powtech 2017.
The talk indicated how there are still many drug products that have come of patent but do not yet have generic equivalents available and how there is a drive from the regulatory bodies to make health care more accessible and so they are producing many guidance documents to help address this.
I gave an overview of a proposed workflow for developing generic drug …

What is the maximum viscosity for DLS?

Is there a maximum viscosity for DLS measurements?
 
The Malvern Zetasizer can determine particle size by dynamic light scattering (DLS). In this technique, the intensity fluctuations are analyzed to find the corresponding diffusion coefficient that led to the fluctuations. The translational diffusion coefficient Dt of a particle is inversely related to its size and the viscosity of the dispersant (or more accurately the hydrodynamic radius rH and viscosity η).
This relationship can be used to predict detectability limits of the technique in general, and this is how we explore the idea of …
