Quantitative Electron Probe Microanalysis
The recognition and understanding of the role of the microstructure in controlling the macroscopic behavior of a material has been a major theme of science and technology throughout the history of NBS/NIST. In materials science, the late 19th century saw the development of the sample preparation procedures we know today as “metallography” and “materialography,” and the emergence of optical micr...
متن کاملThe Present Status of Organic Elemental Microanalysis
The influence of instrumental analysis, i.e., physicochemical methods, has become increasingly important in organic chemistry, but organic elemental microanalysis is by no means an obsolete field. On the contrary, with the development of new methods, the organic chemist obtains the results that he needs for a first orientation on a compound, more quickly and more reliably than ever before. Toda...
متن کاملUncertainty in Quantitative Electron Probe Microanalysis
Quantitative electron probe analysis is based on models based on the physics or x-ray generation, empirically adjusted to the analyses of specimens of known composition. Their accuracy can be estimated by applying them to a set of specimens of presumably well-known composition.
متن کاملFundamental Constants for Quantitative X-ray Microanalysis.
Quantitative X-ray microanalysis requires the use of many fundamental constants related to the interaction of the electron beam with the sample. The current state of our knowledge of such constants in the particular areas of electron stopping power, X-ray ionization cross-sections, X-ray fluorescence yield, and the electron backscattering yield, is examined. It is found that, in every case, the...
متن کاملImplications of Polishing Techniques in Quantitative X-Ray Microanalysis
Specimen preparation using abrasives results in surface and subsurface mechanical (stresses, strains), geometrical (roughness), chemical (contaminants, reaction products) and physical modifications (structure, texture, lattice defects). The mechanisms involved in polishing with abrasives are presented to illustrate the effects of surface topography, surface and subsurface composition and induce...
