Bruker D8 A25 DaVinci X-ray Diffractometer with Mo radiation and focussing mirror optics.Diffractometer and LynxEye™ SuperSpeed Detector. Used for non-standard set-ups.
Can be used with either:
1) Mo radiation and focussing mirror optics.
2a) Cu radiation, Bragg Brentano
2b) Cu radiation, parrallel beam optics

Right now we are in the process of aligning the instrument with the Cu-tube, and test out capabilities of SAXS (Small-Angle X-ray Scattering). With the parallel beam optics fitted, this instrument will also be well suited for Grazing-Incidence Diffraction. |
Well suited for (Mo radiation):
- 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 (Mo radiation):
- High d-spacing materials (e.g. large pore zeolites, MOFs)- the low angle peaks may be missed due to the short wavelength.

Typically 3-155 degrees 2θ (0.46 Å-1 < Q < 17.3 Å-1, 13.6 Å > d > 0.36 Å) (for Mo-radiation)
