Transmission Electron Microscope (TEM)
Equipment : Transmission Electron Microscope (TEM)
Brand / Type : Tecnai G2 20S-Twin
Function : Transmission Electron Microscope is a microscopy technique where electron beam is transmitted through a very thin speciment (thickness £ 100 nm), and the interactive result is enlarged in the form of an image and displayed with a CCD camera, fluorescence screen, or film sheet.
TEM FEI Tecnai G2 20S-Twin is a 200kV voltage acceleration class TEM with sub Ångström resolution of 0.24 nm (point) and 0.188 nm (line), magnification range of 25x – 1030kx which is equipped with CCD Camera and EDS (Energy Dispersive X-Ray Spectroscopy) facility. With above specification, TEM FEI Tecnai G2 20S-Twin is able to analyze material and biological sample particularly for failure/defects analysis, material phase determination, elemen composition and another imaging purposes with nanometer resolution. Some of the unique feature of this equipment is that it can also be used as STEM, correlative microscopy, observation under cryogenic condition and tomography of 3D macromolecule structure.
