X-ray Powder Diffraction Lab
Location: Lash Miller Lab, 4th floor, Room 437-B.Facility manager: Dr. Srebri Petrov
Equipment:
- Siemens D5000 conventional theta/2theta diffractometer,
- Bruker AXS D8 Discovery with GADDS area detector,
- Bruker AXS SAXS
NanoStar diffractometer for low-theta measurements.
Some experimental analyses routinely carried out in PXRD Lab are:
- Identification of components in pure materials and complex mixtures.
- Quantification of the identified components by various methodological approaches, including Rietveld method,
- Analyses of solid solutions by lattice parameters and Rietvled method,
- Indexing of the diffraction pattern of unknown crystalline substance,
- Characterization and identification of different polymorphous in a mixture,
- Structural refinement of one, or several crystalline components (Rietveld),
- Analyses of thin films on various substrates,
- Determination of degree of crystallinity in presence of amorphous material,
- Microdiffraction x-ray analyses using transmission and reflection mode with 2D-detector,
- Evaluation of the orientation of textured materials (with 2D-detector),
- Small angle measurements (transmission mode) within the range of 0.2°
- 4.0° 2-theta for characterization of ordering of large molecules
