Chambre d'Analyse Spectrométrique en Transmission ou Réflexion (Analysis Chamber for or Reflection Spectrometry) (CASTOR) is a new instrument, operated at the SOLEIL synchrotron facility, dedicated to metrological characterization of thin films with thicknesses in nanometer range. The instrument can combine two X-ray techniques, namely, reflectivity (XRR) measurements fluorescence (XRF) acquisi...

Optical microscopy, UV-fluorescence, XRF FORS spectroscopy Interchangeability identification general type pigments polychromy Greek temples. Example fruitful cooperation between chemists, archaeologists public institutions safeguarding archaeological heritage. Many monuments objects ancient c...

The effects of different doses of Ukrain and/or strontium on the rat teeth intertubular dentine were analysed in cuts perpendicular to the dentinal tubes. To the dentine elemental analysis, scanning electron microscopy (SEM) equipped in XRF (X-ray fluorescence) microprobe was used. Strontium concentration increased from 4.1% in the control group to 5.0% and 6.3% for the groups administered with...

Abstract: The mine dust deposited on sanded surfaces of test samples in the acrylic bonding exercise of March, 1992 was found by x-ray fluorescence analysis to be 0.05 (+0.07, -0.05) ng/cm2. This is well below the level at which mine dust in bonded joints would present a problem for SNO. The efficiency of the adhesive tape used in the XRF analysis for the removal of mine dust from a sanded surf...

Introduction: This paper describes the progress in the development and application of the AEXS instrument to determine elemental abundance by analysis of the excired XRF spectra. The AEXS is a miniature instrument based on the excitation of characteristic X-Ray Fluorescence (XRF) spectra from samples in ambient atmosphere using a focused electron beam. Operation in ambient atmospheres with mode...

Based on micro-Raman spectroscopy (m-Raman), micro X-ray fluorescence spectrometry (m-XRF), X-ray diffractometry (XRD) and optical microscopy, this paper presents the results of our analytical studies on the early Islamic pigments used in the Masjid-i Jame of Fahraj, central Iran. Our investigations showed that ultramarine blue and haematite were used as blue and red pigments, respectively. Mor...

The present study investigates the chemical composition, solubility, and physical and mechanical properties of carbonate hydroxyapatite (CO3Ap) and silicon-substituted carbonate hydroxyapatite (Si-CO3Ap) which have been prepared by a simple precipitation method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray fluorescence (XRF) spectroscopy, and inductively couple...

Sulfur and iron concentrations in wood from three 17(th) century shipwrecks in the Baltic Sea, the Ghost wreck, the Crown and the Sword, were obtained by X-ray fluorescence (XRF) scanning. In near anaerobic environments symbiotic microorganisms degrade waterlogged wood, reduce sulfate and promote accumulation of low-valent sulfur compounds, as previously found for the famous wrecks of the Vasa ...
