X-Ray Spectrometry, 2011
We utilized an audio digitizer in energy‐dispersive X‐ray fluorescence (EDXRF) with a silicon drift detector and achieved a full width at half maximum (FWHM) of 178 eV at Mn Kα (92‐µs peaking time). To confirm the ability of EDXRF with an audio digitizer, we also examined energy versus ...

X‐Ray Spectrometry, 1998
Elemental chemical speciation by measuring x-ray energy shifts has been carried out by various authors in the past, using tube excitation and wavelength detection. Among the most intense determined shifts are those of vanadium compounds; further, vanadium speciation determination seems to be even more important than total element analysis. In this work,

Figure of merit for spectrometers for EDXRF
X-Ray Spectrometry, 2012How should one select the best detector for a particular measurement in energy dispersive X‐ray fluorescence (EDXRF)? How should one select the optimum system configuration, i.e. the best shaping time and beam current? Manufacturers provide a variety of specifications, such as energy resolution and maximum count rate, but these are indirectly related ...

Application of factor analysis in EDXRF
Fresenius' Journal of Analytical Chemistry, 1997The application of factor analysis in EDXRF as a method for evaluation of elemental concentrations and calculation of net peak areas is demonstrated in two examples. A quantitative PCR-analysis of sulphur interfered with by molybdenum could be performed by using the XRF-spectra as input with a standard error of analysis (SEA) below 0.2 mg/g for aqueous

Analysis of Industrial Glass by Portable µ-EDXRF
Advanced Materials Research, 2008Portable energy-dispersive micro X-ray fluorescence spectrometry (-EDXRF) is a useful device for non-destructive chemical analysis of different materials. Despite its evident potential in the fields of glass analysis, only few archaeometric studies have been performed yet.

Direct determination of metallic impurities in graphite by EDXRF
Applied Radiation and Isotopes, 2010Energy dispersive X-ray fluorescence (EDXRF) methods have been developed for the direct determination of 14 trace metallic impurities in graphite powder without any need for sample dissolution. Using synthetic standards, calibration curves were established for different elements after optimizing the spectrometer parameters.

The Effective Use of Filters with Direct Excitation of EDXRF
Advances in X-ray Analysis, 1979AbstractPrimary beam transmission filters in energy dispersive X-ray fluorescence (EDXRF) analysis are used to shape the spectral output of the X-ray tube. The effective use of these filters allows the optimization of excitation conditions for each different analysis.

Advances and Enhancements in Light Element EDXRF
Advances in X-ray Analysis, 1987One of the strongest analytical qualities of energy-dispersive x-ray fluorescence (EDXRF) is the wide range of analyte elements that can be detected and analyzed. Historically, the technique has covered all the elements from sodium (Z=11) and above. A useful measure of specific spectrometer performance is analyte sensitivity.

EDXRF and micro-EDXRF studies of Late Bronze Age metallurgical productions from Canedotes (Portugal)
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2007Abstract Metallurgical production in Central Portugal during the Late Bronze Age was primarily based on copper–tin alloys, despite influences from the Atlantic area where copper–tin–lead alloys are common. Metallic artefacts from archaeological site of Canedotes (Central Portugal) were analysed by EDXRF to establish the type of alloys present ...

EDXRF and ICP-MS analysis of environmental samples
X-Ray Spectrometry, 1998In an inter-analytical method comparison, energy-dispersive x-ray fluorescence (EDXRF) (radioactive source and x-ray tube based systems), inductively coupled plasma mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectrometry (GF-AAS) analyses were carried out on seven international biological reference materials and environmental ...
