Single crystal diffraction
For single crystal diffraction we operate a Bruker D8 Venture diffractometer using Mo radiation equipped with a PHOTON III detector. The diffractometer is located in our labs and is shared with the AG Chemische Kristallographie fester Stoffe in the Faculty of Chemistry and Biology. The diffractometer can be equipped with a cryostream for low temperature measurements down to 100 Kelvin. A hot air blower is available upon request.Typically complete difraction data sets may be obtained for crystal structure analysis of single crystals of about 100-400 µm diameter. Determination of orientation only is also possible for large crystals up to several mm. Extremely small amounts of powder may be subjected to rotation measurements to achieve powder patterns (however, with rather low resolution in reflection widths) - usually use powder XRD for small samples due to better resolution
Powder Diffraction:
For powder diffraction experiments we operate threediffractometers:
- Panalytical X'Pert Cu-Radiation, Bragg-Brentano Geometry
- D8 Discover Cu-Radiation, Bragg-Brentano Geometry, shared with AG Chemische Kristallographie fester Stoffe in the Faculty of Chemistry and Biology
- D8 Advance Cu- and Mo-Radiation, Bragg-Brentano or capillary transmission geometry, shared with AG Mechanische Verfahrenstechnik, IWT
- In-situ variable temperature measurements are possible.
