X-ray Diffraction (XRD) laboratory

 
Home Facilities Facility X-ray Diffraction (XRD) laboratory
Presentation

The X-ray Diffraction (XRD) laboratory at the Institute of Environmental Assessment and Water Research (IDAEA), as part of the Consejo Superior de Investigaciones Científicas (CSIC), aims to provide a high quality service to CSIC research groups as well as other public and private organizations.

XRD is the reference analytical technique for the study of the mineralogical composition of a wide range of materials, organic and inorganic, natural and synthetic. The XRD pattern of a substance is, therefore, like a fingerprint of the substance. Materials can be minerals, metals, ceramic, glass, plastic, drugs, paper among others. Samples may be in powder form, solid, tablets and thin films. The shape and size can be quite variable.

Application fields

Crystallography, mineralogy, organic and inorganic chemistry, analytical chemistry, geology, soil science, metallurgy, ceramics, pigments, pharmaceuticals, materials science, environmental science, archaeology, restoration of architectural, construction, mining and  biotechnology, among others.

Equipment

Two fully functional diffractometers:

  • Bruker D8 Advance X-ray diffractometer is a θ-θ instrument, primary Göbel mirror (parallel beam geometry), with Cu anode, and SOL-X solid state (or scintillation counter) detector. It is used for routine identification of unknown materials and Grazing Incidence analysis. It is particularly suitable for the analysis of materials that emit fluorescence such as ferrous materials.

  • Bruker D8 Advance A25 X-ray diffractometer is a θ-θ instrument for powder samples analyses. This instrument is configured with a Cu x-ray tube, a number of slits and filters, with the possibility of switching between Bragg-Brentano geometry (beam focus) and Göbel mirror (parallel beam), a rotating sample holder, and a position sensitive LynxEyeXE detector. This instrument offers the option of turning the sample during the analysis and an automatic sample exchanger with 90 positions. It is used for routine identification of unknown materials, quantitative phase analysis and other applications.
