FEI Announces Titan ETEM for Energy, Environmental and Chemical Research
Product News Jun 26, 2008
FEI Company has announced the release of the Titan™ 80-300 environmental transmission electron microscope (ETEM). The Titan ETEM is the premier solution for chemical research at the atomic scale, and is a significant advance for studying materials and processes of importance in the fields of energy and environment.
The ETEM is the newest member of FEI’s Titan TEM family of commercially-available microscopes for direct observation with sub-Ångstrom resolution.
The Titan ETEM’s ability to image the sample in a controlled gaseous environment allows scientists to investigate the fundamental atomic mechanisms of gas-solid reactions, such as carbon nanotube growth, crystal nucleation and growth, heterogeneous catalysis and many other economically-significant processes. Catalysts, for instance, are important in production of fuels, reduction of environmentally-harmful combustion products, and generally throughout the chemical industry for applications concerning energy and the environment.
At the core of Titan ETEM’s capabilities is its ability to deliver high-resolution imaging with gas pressures in the sample chamber as high as a few percent of atmospheric pressure. Conventional TEMs require high-vacuum conditions with pressure levels a thousand to a million times lower. A gas controller permits control of composition as well as pressure.
Heating and cooling holders provide control over a range of temperatures. The ability to select electron beam voltages anywhere between 80 and 300 kilovolts (kV) accommodates a wide range of material and imaging conditions.
