X-ray diffraction (XRD) is the only laboratory technique that reveals structural information, such as chemical composition, crystal structure, crystallite size, strain, preferred orientation and layer thickness. Materials researchers therefore use XRD to analyze a wide range of materials, from powder X-ray diffraction (XRPD) to solids, thin films and nanomaterials.

But what makes a good XRD pattern? How do you know if your peaks have shifted? What if my peaks are broad? What if I am having a high peak to background ratio? This webinar is part of our series of XRD webinars to help you improve your data analysis. In this webinar, our application specialist will discuss:

1. Tips for good quality XRD data collection
2. What makes a good vs bad XRD pattern
3. How to analyse using Malvern Panalytical’s HighScore Plus software
4. Basic profile fitting options to get accurate peak parameters
5. how to perform phase identification and quantification analysis
