GeoMossLab - Mössbauer spectrometer with measuring station dedicated to geological materials studies
Mössbauer spectrometer operating in the high velocity resolution (HVR) transmission mode with two nuclear tracks, proportional krypton detectors, and measurement station dedicated to geological materials studies.
The research is performed as a scientific collaboration.
Mössbauer spectroscopy (57Fe-MS) is a nuclear research method based on the phenomenon of resonant absorption of low-energy gamma radiation. In geochemical research, it is used to analyze the phase composition and determine selected physicochemical parameters of geological materials. Iron atoms, which are probes in the studied material, provide information about their local chemical environment through hyperfine interactions.
57Fe-MS allows for: 1) qualitative and quantitative identification of iron-containing minerals, 2) determination of the Fe2+/Fe3+ ratio, and 3) identification of local crystal coordination geometry.
Measurements are performed on powder samples weighing approximately 10 mg (milligrams) to 100 mg. The method is non-destructive, and after measurement, the sample can be used for further analysis using other methods.
