Lead exposure is widespread among industrial populations in the United States. X-ray fluorescence (XRF) analysis of the lead content of bone offers a promising approach to acquisition of individualized data on chronic lead absorption in occupationally exposed populations. Dosimetric data obtained by XRF will permit accurate definition of dose-response relationships for such chronic consequences...

Management of solid wastes is considered as an economic and environmental issue in the building stone industry. The current study uses raw and calcined calcareous sludge, generated in the stone cutting factories, in order to remove sulfur dioxide. Sludge characterization has been performed, using X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-d...

RECENT DEVELOPMENTS IN HANDHELD X-RAY FLUORESENCE INSTRUMENTATION The introduction of new large area silicon drift detectors to handheld XRF technology expands technique capabilities with greater analytical range and lower detection limits James Pasmore, Director, Business Development [email protected] Thermo Niton Analyzers LLC Thermo Fisher Scientific 900 Middlesex Turnpike, Buil...

According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...

The paper deals with the application of X-ray fluorescence and diffraction for the routing control of a chemical content of an electrolysis cell in aluminum reduction plants. Among two approaches XRD meets technological requirements on accuracy, time limit and the cost of analysis. XRF demonstrates insufficient accuracy because of sample preparation problem.

X-ray based metrology techniques have demonstrated their capabilities for the measurement of critical process parameters on complex microelectronic thin film structures such as layer crystallinity or texture analysis (X-ray Diffraction, XRD), multilayer thickness (X-ray Reflectivity, XRR), material composition (X-ray Fluorescence, XRF) [1]. Achieving the X-ray beam spatial resolution and photon...

The value assignment of candidate Standard Reference Material (SRM) 57b Silicon Metal provided an opportunity to develop an alkali reaction procedure as a precursor to borate fusion for the preparation of test specimens from the metal powder for X-ray fluorescence spectrometry (XRF). Suggested for this purpose by Blanchette (Adv. X-Ray Anal., 45, 415, 2002), the alkali reaction uses LiOH·H2O to...
