In addition, we offer the possibility to measure micro X-ray fluorescence (m-XRF) with the Horiba XGT-9000. Due to a similar atomic form factor of neighbouring elements, distinguishing between these is impossible. In case of a crystallographic disorder the analysis is even more difficult. Exact refinement of the structure is almost impossible without further analysis methods. m-XRF offers the possibility of a (semi-)quantitative elemental analysis. The Horiba XGT-9000 is designed to analyze single crystals as well as bulk samples up to 1 kg and an volume of up to 45 cm x 50 cm x 8 cm. The light element detector allows the measurement down to carbon. There is a transport container which can be filled in the glovebox, so that the sample is not exposed to the ambient air at any time. The sample can be measured under (partial) vacuum and under helium purge, which gives the opportunity to meassure even liquids with vapour pressure or biological samples. A transmission image could additionally be recorded for each measurement. It is also possible to use m-XRF independently of single-crystal structure measurements.
