Geochemistry and Radio Isotope Laboratories

Microorganisms interact with their environment as they produce and and consume dissolved compounds that will therefore become depleted or enriched in their surrounding, mainly in the pore water. Analysis of dissolved compounds is therefore a prerequ…
HELGES – Clean Laboratory for Cosmogenic Nuclides

Within HELGES, we have more than 100 m² of clean lab space is available for separation of meteoric and terrestrial cosmogenic nuclides. We prepare wide-ranging sample substrates for meteoric cosmogenic nuclides (e.g. rocks, sediments, soils, river w…
HELGES – Clean Laboratory for Stable Metal(loid) Isotopes

Within HELGES we have a ISO 6 metal-free clean laboratory, dedicated entirely to blank-sensitive metal(loid) geochemistry. Numerous ISO 4 laminar flow hoods are available for the preparation of wide-ranging sample substrates for non-traditional stab…
HELGES – Mineral Sorter

The mineral sorter is suitable for separating minerals from sediment in which the minerals to be separated differ in brightness and color. After previous sieving, the dry sediment is sorted into light and dark parts up to a maximum grain size of 1 m…
HELGES – Sample Digestion System

Our laboratory is equipped with one of the latest sample digestion systems. The Multiwave can digest samples of all kinds - e.g. food, environmental, pharmaceutical and, of course, geological samples. The samples can be digested at up to 300°C and 2…
HELGES – Sample Preparation Laboratories

Samples of all kinds are pretreated in our sample preparation laboratories. Samples are usually first dried, sieved or separated into magnetic or non-magnetic components in a magnetic separator based on their magnetic properties. Separation based o…
Laboratory for Dendroclimatology

The Dendroclimatology Laboratory serves for the reconstruction of temporal and spatial variability of the climate of the past utilizing multi-parameter tree ring analysis.

Aims:

  • to reconstruct the temporal and spatial variability of the climate of…
Laboratory for Tephrochronology

Tephra, the Greek word for ash, is used to describe any material that is ejected by a volcano into the atmosphere (pyroclasts). Tephra includes dense blocks and bombs (> 64 mm), and lighter materials such as scoria, pumice and ash (< 2 mm). As one m…
Laboratory for Thin-section Preparation

The laboratory for thin-section preparation is specialized in the preparation of thin sections of soft and unconsolidated lacustrine and marine sediments, soils, hygroscopic sediment samples such as salts and clays, and freeze cores, as well as of h…
Magentic Archives of System Earth

The Laboratory for Geomagnetism in Space and Time analyzes the magnetic properties of sediments and rocks to reconstruct temporal variations in the Earth's magnetic field as well as past climate and environmental conditions. Parameters such as magne…
Mineral Separation Laboratory

The Mineral Separation laboratory is designed for performing chemical cleaning and purification of minerals. The fume hood in the lab is suitable for using hydrofluoric acid, in addition to other more commonly used acids. Four hot-dog rollers that s…
Molecular Microbiology Laboratories

Molecular microbial ecology is crucial for understanding the role of microorganisms in ecosystems, as it provides insights into microbial diversity, interactions, and functions at the molecular level. Our labs utilize advanced techniques for environ…
Omics Lab

The Omics Lab is currently equipped with all facilities to carry out DNA extractions, polymerase chain reactions (PCR) and gel electrophoresis. Current research includes the biodiversity and functions of cryophilic microbiomes with the focus on snow…
Organic Microbial Geochemistry Lab

Processes related to the solvents extraction of snow and ice algae or particles are conducted in the Organic Microbial Geochemistry Lab. These processes are done in combination with ultrasonic bath, shaking, and solid phase extraction. Evaporation o…
Organic Surface Geochemistry Laboratory

In the Organic Surface Geochemistry Lab (OSGLab) of the Geomorphology section, the smallest of molecules and isotopes open a door to the past. In the OSGLab we conduct research on regional differences of the causes and effects of past climate change…
PISA – Sample Preparation Lab

Sample preparation instruments are available for all kinds of samples for scanning electron microscopes and transmission electron microscopes: Gold-Palladium Sputter Coater - Leica; Carbon Coater - Leica; Cryo Sample Preparation - Leica; Gatan Model…
Precision Preparation Laboratory

The Precision and Rock Preparation Laboratory, together with the Central Workshop and the High Pressure Development Laboratory, provides essential service infrastructure for all experimental work at the GFZ. Test specimens made of solid rock and cer…
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…
Wet & prep Chemistry

The preparation laboratory includes facilities for the extraction of the soluble organic matter from sediments, sedimentary rocks, coals, microbial cultures and water samples using flow-blending-extraction and ultrasonic-extraction tools. Further, m…
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…
