Short Description
The Bruker D8 Advance X-ray powder diffractometer II is a device for the phase-analytical and structural characterization of powders and thin layers. It is equipped with a fast detector (3rd generation Lynxeye) and enables measurements in transmission and reflection mode. The device is additionally equipped with a high temperature chamber (Anton Paar HTK-1200) for in-situ measurement up to 1200 ° C and an electrochemical cell (El-Cell) and an automated xyz table for in-operando measurement of electrochemical reactions.

Methods & Expertise for Research Infrastructure
X-ray powder diffractometry is the standard method for the qualitative and quantitative determination of the phase composition of powder samples. It is a versatile, non-destructive method that can also provide detailed information about the atomic structure (crystal structure) of both naturally occurring and synthetically produced materials. With the help of appropriate software, Rietveld refinements of the measurement results can be carried out, and thus quantitative phase compositions can be determined and crystal structures refined. Applications can be found in the area of phase identification, e.g. flue gas cleaning and filter residues, ceramics, paints, rocks, ancient finds, sediments, and clay mineral analysis, as well as quantitative phase determination, e.g. for cement clinker, ores, or phase conversion in chemical reactions. With this diffractometer, in-situ / in operando measurements of the course of electrochemical reactions and in-situ high-temperature investigations up to 1200 ° C can be carried out. The xyz table also allows the scanning of coatings and thin films.
