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 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.
