used X-ray fluorescence spectrometer, X-ray diffractometer, X-ray photoelectron spectrometer, and field emission electron probe microanalyzer to study the composition of heavy products in fine coal powders separated by ultrasonic vibration gas-solid fluidized bed.
Spatial resolution of x-ray microanalysis in the (S) TEM is limited by the initial electron probe size and by subsequent beam broadening in the foil.
Pharmaceutical analogs for vegetative gelatin differ in elemental composition, which can be determined using the electron probe microanalysis [4].
The centre will be equiped electron probe micro analyser, In Inductively coupled plasma mass spectrometer, X-ray fluorescence Spectrometer, X-ray diffraction spectrometer, Raman Spectroscopy and an Atomic absorption spectrometer.
The Cathodoluminescence Universal Extension (CLUE) for imaging and spectroscopy analysis from Horiba Scientific provides high-resolution spectral information with the spatial resolution of an electron probe. CLUE features a wide spectral range from UV-Vis to IR, fast CL imaging, CL spectroscopy for detecting trace elements in natural and synthetic minerals, and hyperspectral mapping.
The gemstones have been confirmed as topaz, aquamarine, tourmaline (schorl-foitite), goshenite, garnet (almandine-spessartine), epidote (zoisite-clinozoisite), quartz and fluorite by using various instrumental techniques such as X-ray diffractometer, electron probe micro-anlayzer and scanning electron microscope.
The higher brightness and smaller source size of the FEG produce a smaller, sharper electron probe with a larger probe current, resulting in enhanced atom-by-atom imaging and chemical analysis.
