Using the computer tomograph METRIS XT H 320 LC, materials can be investigated 3-dimensionally. Sample sections of up to approx. 300 mm high can be scanned in the beam path of the 225 KV - 320 KV modular, micro-focus tube. In this way, wall thicknesses between 20 mm and 100 mm can be irradiated depending on the material and the resolution requirements. This enables 3D reconstructions of the test volume to be undertaken using a resolution of up to 15 microns.
A series of structural properties of crystalline samples can be characterised using the PANALYTICAL X-ray diffractometer EMPYREAN. The fully modular system having a vertical goniometer serves to carry out the most diverse tasks in the field of X-ray diffraction: Phase analyses, texture and stress analyses, non-ambient analyses, reflectometry and thin-film analyses. The diffractometer is also furnished with a reaction chamber which was specially developed for investigating solids and solid-gas reactions at up to 900 °C and 10 bar.

By means of simultaneous TGA-DSC, synchronous measurements of the solid’s weight changes can be measured as a function of temperature and time, and the transformation temperatures and changes in enthalpy can be determined for controlled temperature changes. In addition to this, investigations can also be performed using different gases by a water vapour generator and gas control.
