In our earlier webinar series - “Better XRD data quality and interpretation”, senior XRD application specialist, Dr Daniel Lee, demonstrated how to perform crystallinity calculations of amorphous samples. He demonstrated how it could be applied across industries including cement, polymers, pharmaceuticals and more. And one of the techniques used was Rietveld refinement.

As you’re aware, Rietveld refinement is a technique described by Hugo Rietveld to characterize crystalline materials. The neutron and X-ray diffraction of powder samples results in a pattern characterised by reflections (peaks in intensity) at certain positions. Rietveld refinement involves the fitting of a calculated profile and background to experimental data. There are several considerations when performing this methodology. And its success also rests on the experience of the user.

And that is why Malvern Panalytical is organising this session to discuss in greater depth about the technique. Back by popular demand, senior XRD application specialist, Dr Daniel Lee will discuss the fundamentals of Rietveld refinement as well as where its applications. He will provide a step by step tutorial using the latest HighScore Plus version 4.9. Dr Lee will demonstrate how calculate a diffraction pattern from a crystal structure, how to simulate a diffraction pattern and how to manually refine a model to match experimental data. He will be using tutorials from our HighScore Plus software as well as data patterns collected from our latest XRD detector, 1Der, which supports sharp monochromatic peaks and tackles fluorescent samples with ease.
