  • 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
