Electron Microprobe Analysis Lecture Notes
The electron microprobe provides a complete micrometer-scale quantitative chemical analysis of inorganic solids. The method is nondestructive and utilizes characteristic Xrays excited by an electron beam incident on a flat surface of the sample. This course provides an introduction to the theory of X-ray microanalysis through wavelength and energy dispersive spectrometry (WDS and EDS), ZAF matr...
متن کاملThe Electron Microprobe as a Metallographic Tool
The electron microprobe (EMP) is an electron optical instrument in which compositional and topographic information are obtained from regions ~lban in diameter on a specimen. Photographs of compositional and topographic changes in 1-mm 2 to 20-/din 2 areas on various types of specimens can also be obtained which are strikingly similar to optical photomicrographs. This paper discusses the various...
متن کاملElectron microprobe analysis of lunar samples.
Plagioclase feldspar, clinopyroxene, and ilmenite in a polished thin section of a type A crystalline rock were analyzed. The clinopyroxene grains are compositionally variable, and both high Ca and low Ca phases are present. The plagioclase is compositionally homogeneous. The ilmenite is chemically homogeneous except for occasional, small areas of high local chromium concentration. Accessory min...
متن کاملElectron-microprobe age mapping of monazite
High resolution X-ray maps of Th, U, Pb, and Y in monazite can be used to construct age maps, which reveal the continuous spatial distribution of ages in a single grain of monazite. The age mapping algorithm and three examples are presented to illustrate the capabilities and applications of this mapping technique, the insights it can provide into monazite geochronology in general, and its limit...
متن کاملMinimizing Errors in Electron Microprobe Analysis.
Errors in quantitative electron microprobe analysis arise from many sources including those associated with sampling, specimen preparation, instrument operation, data collection, and analysis. The relative magnitudes of some of these factors are assessed for a sample of NiAl used to demonstrate important concerns in the analysis of even a relatively simple system measured under standard operati...
