Brillouin-Interferometry

Brillouin-Interferometry

Knowledge of the elastic properties of geomaterials at high P-T conditions plays a central role in determining the composition of the Earth's interior. The Brillouin interferometer at the GFZ Helmholtz Centre for Geoscienc…
CLEAR Lab "The Color of the Earth's Mantle"

Within the research group CLEAR we endeavor to understand large scale geological processes that operate deep inside planets. Our approach is to recreate high pressure-temperature conditions in the laboratory and examine various physical properties o…
Fourier Transform Infrared (FTIR) Spectrometer

In our lab we use a FTIR-spectrometer Vertex 80v manufactured by Bruker. It is equipped with various light sources, beam splitters and detectors to operate from 25.000 cm⁻¹ to 80 cm⁻¹. The maximum resolution is 0.25 cm⁻¹.

An attached IR-microscope …
High P and T Synthesis Laboratory

For high-P/high-T experiments, we offer various kinds of piston-cylinder- and multi-anvil presses, which are utilized for conditions ranging from the crust to the uppermost lower mantle. In detail, the High P and T Synthesis Laboratory includes the …
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, expe…
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…
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…
Piston Cylinder / Multi Anvil Press

The static 1000 t laboratory press of Max Voggenreiter GmbH can be operated either with a Walker module as a multi anvil press or via a second hydraulic cylinder with a piston cylinder module (diameter 12.7 mm).
Piston Cylinder Press

To investigate the pressure/temperature regime of the Earth´s crust and shallow parts of the upper mantle, at the GFZ three piston cylinder presses are installed and run. Two of the three presses are non-endloaded piston cylinder apparatus ("Johanne…
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 …
Rotating Multi-Anvil Press

A Rotating Multi-Anvil Press constructed by Max Voggenreiter GmbH is installed in the high-pressure hall of the GFZ. The apparatus consists of an 800 tons hydraulic press and a Walker-type multi-anvil module. The whole apparatus is rotatable by 360°…
X-Ray Diffraction Methods

For X-ray diffraction characterisation of solid materials, we hold two STOE STADI-P powder-X-ray diffractometers. Collected pattern are processed with the GSAS-software for Rietveld refinement.

For the crystallographic orientation of single crystals…
