Single Crystal X-Ray Diffractometer (SCXRD)

Crystal Structure Determination

The new Bruker D8 Quest is a state-of-art fixed chi-stage diffractometer equipped with microfocus Mo Kα radiation and mixed-mode detector. This superior crystallographic tool allows detailed insights into the structural properties of minerals and synthetic analogues.

The focus of our research activity is:

  • Phase transitions under non-ambient conditions
  • Twinning and order-disorder structures
  • Crystal chemistry of minerals and related materials

Technical data

  • Detector: The PHOTON III features the largest monolithic active area of any pixel array, no gaps due to the use of a single wafer-scale silicon sensor, single-photon sensitivity no charge sharing effects, zero counting losses.
  • Source: The Mo-Microfocus IµS 3.0 provides up to twice the intensity of conventional microfocus sources. High intensity means higher performances with small (up to tens of micrometers) weakly scattering crystals.
  • Software: Apex 3 is the most comprehensive software package for single-crystal X-ray diffraction from data collection to structure solution and refinement.
