The ElMiE Lab is a research-oriented facility and part of the Helmholtz center in Potsdam. The ElMiE – Lab offers the sample preparation and analyses of geological or environmental inorganic samples for element concentrations and mineralogy of inorganic materials. Laboratories and instruments associated with the ElMiE Lab include the XRD, XRF, …

The lab contains devices that can be used to monitor chemical and physicochemical parameters in natural and synthetic geothermal fluids. For instance,

• A versatile fluid-chemical monitoring unit (“FluMo”) has been developed that enables online and in-situ measurements of a variety of physico-chemical parameters at different surface locations of a geothermal fluid loop.
• The Fluidflow Monitor and Reactor Unit (FluMoRe), consisting of two 50 L stainless steel vessels, enables storage and …

The Planetary Emissivity Laboratory (PEL) is a special sub-session of the Planetary Spectroscopy Laboratory (PSL) of the DLR in Berlin, devoted to emissivity measurements in of samples from low/moderate to high temperature (temperature range from 300 to above 1000 Kelvin).
Emissivity measurements are recorded by using an external emissivity chamber (DLR-custom-designed) attached to a Bruker Vertex80V FTIR from the visible to the far-IR (from 0.4 to 150 µm), with a high SNR. Induction system …

The GFZ spectroscopy laboratory supports advances in optical and thermal remote sensing for the definition of new sensors for spaceborne missions, for the development of methodologies toward improved surface properties characterization, and for the development of standards and protocols. We are focusing on the geosphere applications (minerals and soils), agricultural areas, and arid regions of the world (deserts, arctic) that are subject to erosion and degradation under climate change.

The wavelength dispersive X-Ray fluorescence spectrometer S8 Tiger 4 KW (Bruker) enables the detection of major and trace elements in one run. The chemical composition of rocks, minerals, ore and soil samples, and building materials can be measured in the form of powder tablets and glass beads at the lower ppm-level. Our element spectrum ranges from elements with mass 9 (F) to 92 (U).

The X-Ray Fluorescence (XRF) Lab houses a Bruker S8 Tiger X-Ray fluorescence sequence spectrometer that is used for quantitative analysis of the main and trace elements of bulk rock and mineral samples. Element contents as low as the parts per million (mg/g) range can be obtained by XRF from bulk samples that were previously either finely ground and pressed into a tablet or molten and subsequently cast into a glassy disk. The analyser can be used on-site as well as for sample-based research …

A mobile XRF device from Thermoscientific Niton XLt3 is applied to determine major, minor, and trace element contents (K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Y, Zr, Pb, Th, U) in solids (non-destructive).

For routine X-Ray fluorescence analysis, powdered sample material is fused to a glass disc. Therefore, the powered samples (grain sizes < 62 µm), as well as two Fluxana-samples are dried at ~100 °C, weighed, and melted on different heaters at temperatures between 400-1150 °C. The melt is then quenched to a glass disc and analyzed. We analyze major elements (wt% oxide) and some trace elements (ppm). Analyses are done with a PANalytical AXIOS Advanced.
The XRF Lab is associated to the [ElMiE …
