Microscopy and spectroscopy
Summary
Microscopy and spectroscopy at Georessources
What are microscopy and spectroscopy?
Microscopy allows matter to be observed at very small scales. Depending on the techniques used, magnification ranges from a few units to 1 million. Spectroscopy allows the chemical nature and structure of matter to be analyzed through interaction with radiation. Microscopy and spectroscopy can be combined.
The specificities of microscopy and spectroscopy at GeoRessources
Microscopy covers a wide range of 2D and 3D techniques:
♦ optical,
♦ electronic,
♦ Raman,
♦ infrared,
♦ XRF,
♦ mass spectrometry and X-ray tomography.
When laboratory techniques have a field equivalent, it is generally available and therefore also allows for remote monitoring and analysis. There are strong links with geochemical characterizations and experimentations.
À GeoRessources, les expertises en microscopie et spectroscopie sont portées par 5 plateformes techniques
