A private laboratory specialized in the analysis, testing and failure analysis of materials since 1993

This equipment can quickly provide information on the morphology and elemental composition of a solid object. Its great ease of use, flexibility for viewing highly variable extension fields on massive samples, and the extent of its depth of field make SEM a vital tool in the exploration of the microscopic world.
It consists of two coupled devices:

- The SEM : an electron microscopy technique based on the principle of electron-matter interactions, capable of producing high resolution images of the surface of a sample.

- The EDS microanalysis : the EDS detector receives photons emitted by the material due to electronic excitation, and sorts them according to their energy. Each energy value being characteristic of the energy level of a chemical element, it is possible to identify the elements contained in the material.

This technique provides information that is simultaneously morphological (images) and chemical (elemental composition) of a sample.
