Currently, the electron microscope platform of the State Key Laboratory of Elemento-organic Chemistry consists of one Tecnai G2 F20 S-TWIN Field Emission Transmission Electron Microscope (from American FEI Company), assisted with an integrated STEM system, and an integrated Energy Dispersive Spectrometer system. The transmission electron microscope is characterized by its high resolution and high magnification, with acceleration voltage of 200KV, beam spot drift rate of 0.675nm/min, image point resolution of 0.24nm, and image linear resolution of 0.102nm. Major applications of this transmission electron microscope is in observing fine material’s patterns and organizational structures, and providing relevant information such as crystal structures, sample micro-area chemical compositions, and element distribution (line scanning, surface scanning) of selected areas.
