X-Ray Mapping Using Multiple-EDS and WDS Detectors
High quality x-ray mapping (XRM) has been used for over 30 years by experienced wavelength dispersive spectroscopy (WDS) operators. Manufacturers have been developing similar techniques using energy dispersive spectroscopy (EDS) over the last 20 years. This has been generally unsuccessful due to a number of problems such as poor computer specifications, cost, time to map and generally poor peak...
متن کاملEPMA WDS Peak Position Analysis of Mineral Chemistry in Fossils
Frequently in EPMA, the chemistry of an analyte (that is, the oxidation state and bonding of the elements in the material) is inferred from the composition, by stoichiometry or some other means. While this practice is usually adequate for determining the identity of pure single-phase materials, the results are often inconclusive when attempting similar analyses of complex mixtures composed of m...
متن کاملEPMA WDS Quality Assurance: Materials and Methods
The chief product of an analytical laboratory quality assurance (QA) program, ultimately, is confidenceconfidence that the analysis of any specimen sent to any laboratory participating in the program will be consistent, correct within tolerance, and interchangeable with equivalent analyses of related specimens performed by any other laboratory in the program. In order to maximize confidence, t...
متن کاملCompositional Mapping by EPMA and μXRF
We present methods combining backscattered-electron (BSE) mosaic imaging, quantitative spot-mode electron-probe microanalysis (EPMA), and quantitative compositional mapping by EPMA and micro-xray fluorescence (μXRF) to provide a framework for detailed analysis of terrestrial and lunar samples. BSE imaging provides a base map for the characterization of samples by EPMA. Recent developments in im...
متن کاملApplication of portable X-ray fluorescence (pXRF) for heavy metal analysis of soils in crop fields near abandoned mine sites.
To get representative soil samples, a sampling method was verified for crop fields in the vicinity of abandoned mine sites. Application of appropriate sampling or analytical methods is very important as it affects the costs, time, and accuracy of the refined investigation of soil contamination. Two-time sampling for each crop field was conducted to verify the reproducibility of a zigzag method ...
