Scanning Electron Microscopy Findings With Energy-Dispersive X-ray Investigations of Cosmetically Tinted Contact Lenses
OBJECTIVE To investigate the surfaces and principal elements of the colorants of cosmetically tinted contact lenses (Cos-CLs). METHODS We analyzed the surfaces and principal elements of the colorants of five commercially available Cos-CLs using scanning electron microscopy with energy-dispersive x-ray analysis. RESULTS In two Cos-CLs, the anterior and posterior surfaces were smooth, and col...
متن کاملEnergy-dispersive x-ray microscopy to trace gadolinium in tissues.
An electron microscopic technique, energy-dispersive x-ray (EDX) analysis, was applied to rat tissue specimens containing gadolinium diethylenetriamine-pentaacetic acid (DTPA). EDX spectroscopy was able to detect the characteristic radiation spectra of gadolinium from tissues in concentrations as low as 0.005 mmol per gram of tissue. A mapping algorithm allowed the detected spectra to be assign...
متن کاملEnergy-dispersive X-ray diffraction using an annular beam.
We demonstrate material phase identification by measuring polychromatic diffraction spots from samples at least 20 mm in diameter and up to 10 mm thick with an energy resolving point detector. Within our method an annular X-ray beam in the form of a conical shell is incident with its symmetry axis normal to an extended polycrystalline sample. The detector is configured to receive diffracted flu...
متن کاملEnergy dispersive x-ray analysis in the study of pneumoconiosis.
Identification of inorganic substances in the lung is an important step towards the establishment of a cause and effect relationship in the study of pneumoconiosis. The conventional methods for this identification usually require an ashing which makes it difficult to study the localisation of these substances in relation to pathology. A method is described to identify foreign substances in the ...
متن کاملEnergy-dispersive X-ray absorption spectroscopy at LNLS: investigation on strongly correlated metal oxides.
An energy-dispersive X-ray absorption spectroscopy beamline mainly dedicated to X-ray magnetic circular dichroism (XMCD) and material science under extreme conditions has been implemented in a bending-magnet port at the Brazilian Synchrotron Light Laboratory. Here the beamline technical characteristics are described, including the most important aspects of the mechanics, optical elements and de...
