Applications and capabilities
MiniFlex benchtop X-ray diffractometer is a multipurpose powder diffraction instrument that can be used for:
- Phase identification
- Phase quantification
- Percent (%) crystallinity
- Crystallite size and strain
- Lattice parameter refinement
- Rietveld refinement
- Molecular structure
This compact diffractometer offers fast measurements while ensuring high enough quality for further analysis.
Measurements can be carried out on powder samples as well as larger objects with minimal size ≈ 1 cm2 and a flat plane (cutting and polishing partly available).
PDF-4 database is available on the tool. It contains more than 426000 entries and combines the world’s largest sources of inorganic diffraction data from crystals and powders into a single database.
