X-ray Powder Diffraction Laboratory (XRPD-lab)
The X-ray diffraction is the main technique to study the crystalline matter at different level: from finding the phases in an unknown powder to a fine description of the atomic structure of a material. This technique is very versatile because can applied on different field of physics chemistry, biology and material science.
The X-ray Powder Diffraction laboratory is equipped with a Bruker D8 DISCOVER diffractometer.
The instrument is very flexible and can work on different type of solid materials and sample:
- small bioorganic structure (aminoacid and peptides)
- thin film
- industrial materials
- battery materials
The laboratory service usually gives a full data analysis to obtain the main information:
- phase determination and quantification
- cell parameter calculation
- grain size determination
- amorphous phase quantification
- Structure determination of organic and biorganic molecules.
- Micro-diffraction (500/300 μm)
