Ultrastructural analysis

The microtomography system by General Electrics/Phoenix (from 2016) is installed in a seperate laboratory building. The µCT provides high resolution cross-sections of a physical objects (3D models) without destroying the original objects. Operated by the Palaeobiology section, the µCT is in use by various disciplines including material sciences, medicine and archaeology. Please contact Christian Schulbert (0049 9131 85 24851, gzn-pal-rem@fau.de) if you want to use the µCT for your own application.

The scanning electron microscop by the company TESCAN from Brno (Brünn) is operated by the Palaeobiology section. Please contact Christian Schulbert (0049 9131 85 24851, gzn-pal-rem@fau.de) if you are interested in using the SEM.

Mineralogy

Five diffractometers are available at the GeoZentrum via the research groups in Mineralogy and Endogenous Geodynamics. They allow the following applications:
  • Routine analytics, high sample throughput
  • Microanalytic, textures, (GADDS-system)
  • kinematics (D8)
  • Very small sample sizes, kinematics (D5000 with SOLX-detector)

Please find more information on the web pages of the research groups..

Isothermal calorimetry can be used for the time-resolved investigation of cement hydration. The temperature change in the sample induced by endothermic or exothermic reactions is transferred into a heat flow signal. This allows investigating the retarding or accelerating effect of additives. The Erlangen Applied Mineralogy Group operates two commercial TAM Air isothermal calorimeters with eight twin-type channels, each consisting of a measurement and a reference channel. Find more information on the pages of the Mineralogy.

The crystal growth laboratory is equipped with an optical floating-zone furnace type FZ-T-10000H-VI-FAS (Crystal Systems Inc., Japan). Single-crystals with melting points up to 2200°C and maximum diameter of 1 cm can be grown. The temperature is generated by four halogen lamps, each up to 1500 Watts. Please find more information on the pages of the Mineralogy.

Geochemistry and trace analysis

The laboratory for isotopes provides three mass spectrometers for determining stable isotope abundances for carbon, nitrogen and oxygen in solid samples (carbonates, phosphates, sulphates and organic material).

The laboratory for light stable isotopes of the hydrogeology group is specialized in measurements of the liquid phase. It is equipped for measurements of stable isotope ratios of dissolved inorganic carbon (DIC), dissolved organic carbon (DOC) and particulate organic carbon (POC), and oxygen and hydrogen of water. A modified Gasbench system allows for the measurement of the oxygen isotope ratio of the dissolved oxygen (O2, DO) in water. Additionally, carbon and oxygen isotope analysis of organic material and compound specific isotope analysis (CSIA) of organic pollutants can be carried out. Routine analyses in major ions and trace elements as well as field sampling are also performed. Direct link to the Laboratories of Applied Geology

The GeoZentrum Nordbayern is equipped with new, purpose built metal-free Class 1000 geochemistry laboratories laboratories, and state-of-the-art magnetic sector and quadrupole mass spectrometers. These instruments are used to measure the isotope composition of elements such as Sr, Nd, Pb and Hf, as well as mass-dependent isotope variations in elements such as Mo and Sr. A quadrupole ICP-MS is used to measure trace element concentrations in geological materials. We undertake work for external users, and are happy to discuss collaborative projects. Please contact Marcel Regelous (09131 8569602, Marcel.Regelous@fau.de) for more information.

Our thermal ionisation mass spectrometer has 9 Faraday detectors and a secondary electron multiplier, and is used for the precise isotope analysis of small (10-100 nanogram) quantities of Sr, Nd and other rare-earth elements. Please contact Marcel Regelous (09131 8569602, Marcel.Regelous@fau.de) for more information.

The MC-ICP-MS at the GeoZentrum Nordbayern is equipped with nine Faraday detectors, a secondary electron multiplier, and three ion-counting channels. It is used for precise and accurate measurements of the isotopic composition of elements that are difficult to ionise using thermal ionisation methods (e.g. Hf, Th and W), and to measure mass-dependent variations in the isotopic composition of non-traditional elements (e.g. Mo, Li, Ni). The instrument is equipped with an electrostatic filter and retarding potential quadrupole, providing high abundance sensitivity so that we are able to measure very small isotope ratios including 234U/238U, and 230Th/232Th (typically 5 x 10-6 in volcanic rocks). Please contact Marcel Regelous (09131 8569602, Marcel.Regelous@fau.de) for more information.

Geotechnics and petrophysics

Analytical equipment available in the petrophysical laboratory allows the measurment of many petrophysical parameters including porosity, permeability, thermal conductivity and thermal diffusivity. Please find more information on the web pages of the laboratory.
