Got 20 results.
Calorimetry Lab

Differential scanning calorimetry (DSC) is a method of thermal analysis for determining the amount of heat released or consumed by a sample at a defined temperature change. For this purpose, a container with sample material and an empty reference co…
ElMiE-Lab - Elements and Minerals of the Earth Laboratory

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 inorg…
EleMap - Elemental mapping by LA-ICP-MS

The EleMap Lab is devoted to *in situ* analyses of minor and trace elements in minerals and other geological materials. We have a Teledyne Analyte Excite 193 nm excimer laser coupled to a Thermo Scientific iCAP RQ quadrupole ICP-MS and a Thermo Scie…
Gas Analysis

Gas geochemistry is an essential aspect in many areas of research, such as volcanology, environmental research and raw materials exploration.

The GFZ's Gas Geochemistry Laboratory (GGL) routinely analyzes most permanent gases. In addition to the …
Geochemistry Laboratories

The research done in section 3.1 demands precise and accurate analyses of element concentrations and isotope ratios in a wide range of materials (minerals, rocks, fluids and gas) and on samples as tiny as 1 micron in diameter and with just picograms…
Hydrothermal Diamond-Anvil Cell

The hydrothermal diamond-anvil cell (HDAC) can be applied to study fluids, solids and particularly aqueous samples _in situ_ at high pressures and temperatures. Although such cells are usually used at P-T conditions of less than 3 GPa and 850 °C, ex…
Hydrothermal Laboratory

The hydrothermal laboratory is equipped with horizontal and vertical cold-seal pressure vessels for the synthesis of crystals or glasses or to study interactions between minerals/rocks, melts, and fluids at hydrostatic conditions. The hydrothermal l…
ICP-MS Lab

The ELEMENT 2XR is a high-resolution sector field mass spectrometer (HR-ICP-MS) with inductively coupled plasma as an ion source. It is used for the quantitative analysis of element concentrations or isotope ratios. It offers excellent results even …
ICP-OES Lab

ICP-OES is an established analytical method for the determination of elements in the concentration range from μg/l to g/l. It is suitable for analyses of large sample throughputs due to low analysis time.

The configuration of the 5110 ICP-OES wit…
IHPV - Internally Heated Pressure Vessel

In principle, an internally heated pressure vessel (IHPV) consists of a thick-walled pressure vessel sealed by closure plugs at the ends. In addition, there is a pressure inlet/outlet as well as several electrical leads into the vessel for power sup…
Ion Chromatography

Ion chromatography is used to analyze anions in aqueous solutions. This physical-chemical separation process is based on the distribution of the substance into a mobile fluid phase and a solid stationary phase. We analyze mostly chloride (Cl⁻), fluo…
Isotope Geochemistry Labs

The Isotope Geochemistry Labs are equipped with a clean room facility (including several low-blank chemistry laboratories (class 100), sample preparation and ion-exchange chromatography, a set up for isotope systems: Pb, U-Pb, Rb-Sr, Sm-Nd as well a…
Micro-Raman Spectroscopy Laboratory

The Micro-Raman Spectroscopy Laboratory (Sections 3.1 and 3.2) uses a Horiba Jobin Yvon LabRAM HR Evolution Raman spectrometer equipped with a motor-driven x-y table and an Olympus optical microscope. Depending on the experiment two different laser …
Microprobe Lab

The electron microprobe technique allows for nondestructive analyses of smallest parts of materials (in micrometer range) with high precision. Materials that can be analyzed are embedded and polished mineral grains (also gemstones), glass particles …
Noble Gas Lab

The noble gases (or "rare gases") helium, neon, argon, krypton, and xenon are chemically inert. Due to their volatile nature they have a strong tendency to partition into gas or fluid phases and can be used as tracers for the origin and the transpor…
Raman Spectroscopy Laboratory

The laboratory is equipped with two confocal high-resolution Raman spectrometer systems to study fluid and solid samples (from single point analyses and line scans to two- and three-dimensional Raman imaging) at ambient pressure and temperature and …
Rock Preparation and Mineral Separation

The section is well equipped for rock crushing, sieving and milling, preparation of thin and polished sections and grain mounts, and mineral separation by gravimetric and magnetic methods. We maintain central facilities and equipment for cleaning, c…
The Potsdam Ion Microprobe (SIMS) User Facility

The GFZ Helmholtz Centre for Geosciences operates a fully equipped, large geometry SIMS instrument, which is supported by a comprehensive spectrum of peripheral instrumentation. The SIMS laboratory is an open user facility intended to support the ne…
X-Ray Fluorescence Spectroscopy (XRF)

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 temper…
X-Ray Powder Diffraction Analysis (XRD)

An X-Ray Diffraction analysis is a method in which a beam of X-Rays is usually directed at a fine powder of randomly oriented grains of crystalline substances. The X-Rays are scattered in directions that depend on the crystal structure of the sample…
