SEM-EDX analysis of chemical composition of metals and ceramics
Both a routine inspection technique and a powerful investigation method, Scanning Electron Microscopy (SEM associated with Energy Dispersive X-ray spectroscopy (EDX) microanalysis enables a local or comprehensive analysis of the most diverse inorganic materials.
In addition, this technique can be used to perform a quantitative analysis both on solid samples measuring a few centimetres squared and on fragments, particles or residues measuring a few microns.
Some examples of our services:
- Identifying metal alloys
- Verifying the grade of a stainless steel
- Determining the nature of coatings on metallographic cross-sections
- Quantitative analysis of a technical ceramic
- Identifying the phases present in a microstructure
