Transmission electron microscopy holder

The gas reactants and products of the reaction were studied with a mass spectrometer and the solid reaction of the oxidation of iron was studied with Mossbauer spectrometry with electron diffraction. The Mossbauer study of the oxidized iron powder was carried out in a constant acceleration equipment [121], The electron diffraction study of the oxidized iron film, evaporated over a carbon covered transmission electron microscopy sample holder and introduced into the 5L spherical Pyrex glass container, where the Fe evaporation takes place, was carried out with the help of an Hitachi 100C transmission electron microscope [119],... 

Samples for transmission electron microscopy must fit onto a specimen support known as a grid or screen. This grid is a metal mesh screen, generally 2-3 mm in diameter, which fits into the specimen holder of the microscope. Grids come... 

The single analytical instrument that is appropriate for analysis of waterborne asbestos, then, is transmission electron microscopy (TEM). This high-resolution instrument clearly displays the narrowest asbestos fibers on its bright phosphor screen at magnifications of 10,000 X to 20,000 X. When the intermediate lens is focused on the back focal plane of the image, electron-diffraction (ED) patterns can be produced. Amphibole or chrysotile crystalline structures can be positively identified by measuring these patterns. Finally, specific species of amphiboles can be differentiated by EDX detectors inserted near the specimen holder [18].
