Single crystal diffraction is a powerful X-ray technique for structural solution of crystals typically of 20 - 200 microns in diameter. It provides key information on the symmetry and atom positions in these crystals. Usage spans from routine structural work on organic and metal-organic small molecules to highly detailed investigations of heavy metal oxides that can include twins, modulated structures or diffuse scattering.
The X-ray facility at Warwick is equipped with two single-crystal diffractometers. The Rigaku Oxford diffraction SuperNova is a state of the art Kappa geometry goniometer equipped with dual wavelength (Cu/Mo) microfocus X-ray source and an Atlas S2 CCD area detector which allows for extremely fast data collection of the entire Ewald sphere. In addition, it is equipped with an Oxford Cryosystems N-Helix cryo cooling system allowing for data collection down to 25K.
The Gemini R is a Kappa geometry goniometer equipped with dual wavelength (Cu/Mo) fine focus X-ray sources, graphite monocromators, Enhance optics and a Ruby CCD area detector, which allows for extremely fast data collection of the entire Ewald sphere. For low temperature experiments (80 K - 400 K) an Oxford Cryosystems Cobra is attached to the system.
