Energy dispersive X-ray fluorescence (EDXRF) is a rapid, straightforward method to determine sample elemental composition. A spectrum can be collected in a few minutes or less, and elemental content can be determined easily if the detector has adequate energy resolution. Radioactive alpha emitters, however, emit X-rays during the alpha decay process that complicates spectral interpretation. Thi...

KAYMAK, H. C., I. GUVENC and A. GUROL, 2010. Elemental analysis of different radish (Raphanus sativus L.) Cultivars by using wavelength-dispersive X-ray fluorescence spectrometry (WDXRF). Bulg. J. Agric. Sci., 16: 769-774 The aim of this work is to study the applicability of a quantitative WDXRF (Wavelength-Dispersive X-ray Fluorescence) method, for determination of minerals in radish specimens...

PURPOSE Main aim of the present study was to test and show the dissolution of coatings onto Ti6Al4V pedicle screws by both in vitro and in vivo analysis. METHODS Hydroxyapatite (HA) was coated on Ti6Al4V by electrophoretic deposition (EPD). The dissolution of the coatings was tested in vitro. The coating was characterized before and after implantation via pull-out tests, X-ray diffraction (XR...

The use of a portable X-ray fluorescence spectrometer (PXRF) equipped with a miniaturised X-ray tube producing a small 8 mm diameter X-ray beam required the validation of two new sampling protocols for the immediate screening of occupational lead exposure. First, lead in dust and fumes, collected by Institute of Occupational Medicine (IOM) inhalable samplers on 25 mm diameter membrane filters, ...

The paper presents possibilities and difficulties in nondestructive analysis of small multielement single crystals performed by means of X-ray spectrometry techniques: micro-X-ray fluorescence spectrometry (μ-XRF), energy-dispersive electron probe microanalysis (ED-EPMA), and X-ray photoelectron spectroscopy (XPS). The capability of the X-ray spectroscopy techniques in elemental analysis is dem...

Abstract X-Ray fluorescence (XRF) is an effective method for chemical profile analysis of various materials. In earlier times, it only confined to qualitative and quantitative analysis. This wavelength dispersive X Ray (WDXRF) will be used check the nuclear design different Molybdenum compounds. The study relative intensity ratios satellite peaks (Mo) trioxide (MoO 3 ) compounds associated with...

silver coins of alexander of macedonia, until the arrival of parthians in the 1st century bc, have been put in wdxrf in order to determin ag, cu, pb and au as major and trace elements for fineness, debasement and refinement of silver in ancient persia. seleucid kingdom from 4th to 1st century bc was succeeded by several dynasties and kings. but the chemical composition of their silver coins an...

A novel method for preparing thin films was investigated for quantifying gallium and iron in plutonium solutions using WDXRF. This technique was developed to eliminate the potential for radioactive liquid to leak into the spectrometer, decrease specimen preparation time, and minimize waste. Samples were cast in μL quantities onto Kapton, and a surfactant was added to disperse the solution unifo...

Abstract Findings from the archaeological site of Shahr-i Sokhta in eastern Iran include a wide range undecorated, monochrome, and polychrome ceramics with gray, red, buff-colored bodies that date back to period spanning 3200 1800 B.C.E. Given large number variety unearthed Sokhta, provenance these wares has remained subject controversy. Based on compositional data obtained quantitative wavelen...

The C, H, N and O composition of polymers, sometimes called “dark matrix”, is determined by wavelength dispersive X-ray fluorescence (WDXRF). recovery was best for the lowest spectral resolution highest recorded intensity.
