Description

Bruker D8 A25 DaVinci X-ray Diffractometer  with Mo radiation and focussing mirror optics. LynxEye™ SuperSpeed Detector. Used for non-standard set-ups.

Well suited for:
  • 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
  • Pair distribution functions (total scattering analysis)
  • Absorbing samples in transmission
  • In situ studies of solid/gas reactions in flow cell
  • In situ studies on batteries
Not so good for:
  • High d-spacing materials (e.g. large pore zeolites, MOFs)- the low angle peaks may be missed due to the short wavelength.
Stages available:
  • Capillary spinner (mounted most of the time)
  • Transmission sample holder stage
  • Standard sample stage
  • Heat blower for capillary stage
  • Flipstick 9 position sample changer (to come)
  • Automated XYZ stage (to come)
  • Possibility to mount furnace (in future)
