Electron microscopic analysis of asbestos body cores from the Belgian urban population.
Typical ferruginous bodies considered as asbestos bodies (AB) were collected from the lungs of 19 asbestos-exposed and 25 non-exposed urban subjects. Of the 319 body cores analysed by energy dispersive spectrometry (EDS), 315 were asbestos. The non-asbestos cores were talc and crystalline silica. 89.2% of the asbestos cores were commercial amphiboles (amosite/crocidolite), 7% were chrysotile an...
متن کاملElectron 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 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 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...
متن کاملDetermining the Bulk Chemical Composition of Chondrules by Electron Microprobe: a Comparison of Different Approaches
Introduction: A precise knowledge of bulk chemical compositions of chondrules is not only essential for understanding the relationship between chondrules and matrix [e.g. 1], but also for constraining the chondrule forming mechanism [2]. Despite the given importance, relatively few data sets for chondrule bulk chemical compositions are available in the literature, especially for the most primit...
