Details

Tool name: Multi Purpose Powder X-ray Diffraction

Tool ID: RECX-2

Category: Characterization

Manufacturer: Bruker AXS

Model: D8-A25

Tool rate: C

• Determination of precise crystal lattice parameters
• Detailed analysis of materials with known or partially known structures (lattice parameters, bond lengths and angles, thermal parameters)
• Completion of partially solved structures
• Elimination of preferred orientation
• Suppression of fluorescence from Co, Mn and Fe based samples thanks to Mo radiation
• XRD at high T (up to 1200 °C) in air or vacuum
• Spatially resolved measurements on large samples
• Pair distribution functions (total scattering analysis)
• Adsorbing samples in transmission
• In situ studies of solid/gas reactions in flow cell
• In situ studies on batteries
• Capillary and reflection plate sample holders. Other sample shapes can be accommodated using the XYZ stage

 Problems

• High d-spacing materials (e.g. large pore zeolites, MOFs)- the low angle peaks may be missed due to the short wavelength
