This lab is dedicated for the synthesis of redox-active iron mineral phases, as well as their interaction with redox-sensitive trace elements (e.g., As, Cr,) and anaerobic microbes, under oxygen-limited conditions. It is equipped with two anaerobic chamber workstations, setup for liquid degassing to remove O₂, sample autodiluter for trace element analysis and standard chemical laboratory equipment such as analytical balance, centrifuge, fume hood, hotplate stirrer, shaking incubator, oven and …

The lab contains devices that can be used to monitor chemical and physicochemical parameters in natural and synthetic geothermal fluids. For instance,

• A versatile fluid-chemical monitoring unit (“FluMo”) has been developed that enables online and in-situ measurements of a variety of physico-chemical parameters at different surface locations of a geothermal fluid loop.
• The Fluidflow Monitor and Reactor Unit (FluMoRe), consisting of two 50 L stainless steel vessels, enables storage and …

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 and variations in biochemical cycles. In some projects, we can determine the "traces" of climate change down to a decade, in other projects biogeochemical processes are traced over millions of years.
In the laboratory, changes in the carbon …
