Thermal Analysis Platform (PLAT)


The LMI has the entire responsibility of the platform’s equipment, its functioning and its technical and scientific orientations. The platform regroups a very complete assembly of instruments in calorimetric, thermogravimetric, thermo-mechanic and thermo-microscopic analyses, but also couplings of thermogravimetry with gas chromatography and mass spectrometry. Very few platforms and similar competences exist at national level. The platform has an autonomic functioning (except the personnel’s salaries), also assuring the maintenance, replacement and the extension of its instrumental park. It also has an open functioning, either by participating in research projects with the other teams of LMI or with research and industrial laboratories from France, and either in provision of service for academics or industrials.

Head of the platform: Dr. Ing. Rodica CHIRIAC, IR CNRS

Operation : provision of service / collaboration contracts or projects / research activities (industrial & academic partners)

Formation: here
