Gas Mixing Furnace

Temperature: < 1900 °K 

Pressure: 1 atm

Vertical gas mixing furnace (Carbolite-Gero STF 16/180) for glass or crystal synthesis experiments under controlled oxygen fugacity (fO2 conditions)

Gas mixtures of CO, CO2 and Ar/H2 are possible or experiments can be run under atmospheric conditions.

The amount of O2 is measured with a  Zirox XS50B-600 O2-sensor.

Equipment: rapid quench sample holder, gas-tight ceramic tube, water-chilled flanges (top & bottom), and logging units for temperature and oxygen fugacity

Diamond Anvil Cell Lab

Temperature: 1500-5000 K

Pressure: < 100 GPa
 

Our laboratory for diamond anvil cells (DAC) and laser heating has everything needed for our own and our collaborators' high pressure and high temperature research. 

In detail, there is a suite of different types of diamond anvil cells, binoculars, a ruby fluorescence system and a spark-erosion micro-drilling system. The Raman system ist next door.

Gas loading is available for Neon at the German Research Centre for Geosciences (GFZ) Potsdam, section 3.6 

Our CW infrared laser heating system is portable and has been commissioned for in-situ X-ray emission spectroscopy at Petra III, DESY, Hamburg.
