The laboratory for XRF Element Scanning provides qualitative and non-destructive analyses of sediment compositions based on X-Ray Fluorescence. These analyses provide detailed element records and maps that can be used to characterize past depositional, environmental and climatic conditions.
In detail, the lab is equipped with an X-Ray fluorescence core scanner to analyze split core sections up to 180 cm length and diameters between 6 and 12 cm. Further, two micro X-Ray fluorescence scanner …

Bruker M4 Tornado is an energy-dispersive micro-X-Ray fluorescence spectrometer for the spatially resolved analysis of elements with atomic numbers from 11 (sodium). The device can analyze a wide range of samples such as large, inhomogeneous samples such or small particles. The M4 is equipped with capillary optics that realize spot sizes of 20 or 150 μm. Samples: rock sections or crystals, max. 190 x 160 mm; Spot size: 20 μm / 150 μm

The Micro X-Ray Fluorescence (µXRF) Lab houses two spectrometers used for element dirstribution maps and quantitative analysis of the main and trace elements. The Bruker Tornado M4 plus can analyse samples up to 16x20 cm and runs under vacuum to allow detection of low mass elements. The lowest spot size is 20 µm. The Bruker Jetstream M6 can analyse large samples with a maximum mapping size of 60x80 cm. It usually runs under atmosphere (no detection of low mass elements). The spot size is …
