CELDI

CELDI

Newtec has developed, in collaboration with the Marcoule Institut for Separative Chemistry, a sample holder for scanning electron microscopy (SEM).
This device allows in situ and in real time observation of interface phenomena between a solid and a fluid, compatible with all SEM models for solid samples with liquid or gaz circulation in order to :
• Fine characterization of surface phenomena under fluid
• Participate in research, development and innovation in materials sciences (corrosion study, deposition,…) and in life science (cell reaction to a change in its environment).
