X-ray diffraction (XRD)
Laboratory for X-Ray powder diffraction
X-Ray powder diffraction is a non-destructive technique for phase- and Rietveld analysis of crystalline materials.
Determination of:
- detailed phase composition
- quantitative Rietveld analysis
- nanocrystallite-sizes
- lattice parameters
- amorphous content
- 1d-mappings
Our powder X-Ray diffractometer (Empyrean, PANalytical, Almelo, Nl) is working in reflection (Bragg-Brentano) or transmission theta-theta geometry. It is equipped with a Cu tube, a fast PIXcel-1d detector and an automatic 30-position autosampler.
Additional XRD accessories allow to perform various types of measurements:
- sample holder with 0-background (Si-single crystal-holder) for small amount of samples
- Kapton film cover for transmission mode for plastic foils or polymers
- programmable XYZ-solid sample stage for sample positioning and 1d-mapping
- capillary spinner for air-sensitive and highly texturated samples
The instrument runs the X'Pert DataCollector and HighScorePlus software suite for phase and Rietveld analysis, including the ICDD and PDF-3 database.
