X-ray Diffractometry XRD

With the help of X-ray Diffractometry (XRD) the structure of solid state body can be examined. In our institute it is applied mostly for the examination of the structure and crystallinity of the MOFs.


For this, two machines are operative:

For the out-of-plane measurement a Bruker D8 Advance, with which the distances of the lattice planes parallel to the substrate are determined, and

for the in-plane measurement a Bruker D8 Discover, with which the distances of the lattice planes perpendicular to the substrate are determined.

For powder XRD (PXRD) beside the D8 Advance, there is a Siemens D5000 available.
