XRD at Nanolab

We have two X-ray diffraction setups in building 346:

The Rigaku SmartLab primarily for thin film analysis
The XRD Powder for phase analysis of powders

Data analysis

For data analysis, we recommend using Rigaku SmartLab Studio for both thinfilms and basic powder analysis. If more advanced powder analysis is needed a remote desktop with a licens for the Malvern Panalytical software, HighScore is available.

Installing SmartLab Studio II
