In Situ Catalyst Analysis at the Nanoscale Using Protochips Atmosphere 200 Gas E-Cell System
In a special edition of the Microscopical Society of Canada Bulletin, the Protochips Atmosphere 200 was featured as a crucial emerging component of catalyst analysis research.

Catalysts are essential for a number of billion-dollar industries including chemical synthesis, product manufacturing, automotive and renewable energy. The unparalleled spatial resolution and analytical capabilities of TEM’s are uniquely suited for catalyst research. However, for catalyst research, the sample must be imaged in high vacuum rather than the real-world, in situ, environment.

The Protochips Atmosphere 200 Gas E-cell fills the gap between simple holder-based closed cell designs and a dedicated ETEM. The system allows atomic-scale resolution imaging at gas pressures up to 1000° C with extremely low drift, closed-loop temperature control with EDS and EELS compatibility.

Researchers in Xiaoqing Pan’s group at the University of Michigan used the Atmosphere 200 to study high-temperature reduction of a rhodium-doped calcium titanate sample to better understand the self-regulation process under relevant reaction conditions as it occurs.

To learn more about this research and how Atmosphere 200 works in these conditions, the article can be found in the MSC Bulletin Vol 43 No 1 2015-08.
