Dynamic in situ exploration of nanomaterials at the atomic scale with variable gas pressures and temperatures
The Titan™ ETEM is the ultimate in situ high resolution electron microscope to study dynamic behavior of chemical reactions under the influence of variable temperatures and gas pressures at the atomic level.
The innovative E-cell technology in the objective lens pole piece allows in situ S/TEM gas experiments with a mixture of up to four gas inlets with preset partial pressure up to 2 kPa (20 mbar, 15 torr). This unique capability can be combined with the image Cs-corrector and monochromator technology of FEI to explore the dynamic behavior of the morphology, structure, composition and bonding of nanomaterials down to the atomic level.
The Titan ETEM is equipped with a gas mixing unit and a mass spectrometer to control and determine the gas composition at the specimen, which permits full control of in situ experiments and gives detailed information of the gases in the microscope. Additionally, a built-in plasma cleaner allows for cleaning the column after gas experiments. The Titan ETEM in non ETEM mode has the same lateral S/TEM resolution and energy resolution specifications as a Titan 80-300 without ETEM technology. Therefore, it is a flexible tool that is not solely dedicated to in situ applications. The system is based on the world class modular Titan technology in mechanical, electronic and thermal stability and is designed to deliver the ultimate performance in all TEM, STEM, energy filtered TEM (EFTEM), diffraction and electron energy loss spectroscopy (EELS) modes. The flexibility of operating the Titan 80-300 in the voltage range of 80 to 300 kV, allows this important parameter to be optimized to the requirements of the material examined, from ultra-light carbon compounds to ultra-dense heavy metal materials.
Combining all of these enhancements in one, easy to use instrument enables you to explore the dynamic behavior of the nanoworld, and helps you to expand your boundaries with new pioneering scientific results.
