Titan ETEM Themis

The best in situ S/TEM platform gets even better

Understand materials' structure-function relationship by enabling in situ studies at the atomic scale.

In situ observation of structure dynamics at length scales that are characteristic for nanostructures is extremely important to scientists focusing on atomic-scale research.

The FEI Titan™ ETEM Themis builds on the proven Titan ETEM concept-combining both standard S/TEM and dedicated environmental TEM capabilities for time-resolved, in situ studies of the dynamic behavior of nanomaterials.

The Titan ETEM Themis is designed as a fully integrated platform for in situ experiments, such as exposing nanostructures to gaseous reaction/operating environments.
