Available in PDF, EPUB and Kindle. Book excerpt: In 1968, the National Bureau of Standards (NBS) published Special Publication 298 "Quantitative Electron Probe Microanalysis," which contained proceedings of a seminar held on the subject at NBS in the summer of 1967. This publication received wide interest that continued through the years far beyond expectations. The present volume, also the result of a gathering of international experts, in 1988, at NBS (now the National Institute of Standards and Technology, NIST), is intended to fulfill the same purpose. After years of substantial agreement on the procedures of analysis and data evaluation, several sharply differentiated approaches have developed. These are described in this publi cation with all the details required for practical application. Neither the editors nor NIST wish to endorse any single approach. Rather, we hope that their exposition will stimulate the dialogue which is a prerequisite for technical progress. Additionally, it is expected that those active in research in electron probe microanalysis will appreciate more clearly the areas in which further investigations are warranted.

Available in PDF, EPUB and Kindle. Book excerpt: Electron Probe Microanalysis presents a collection of reviews on various aspects of electron probe microanalysis. This book discusses the model for quantitative electron probe analysis. Organized into 14 chapters, this book begins with an overview of the various kinds of microanalysis followed by a discussion of the advantages that can be derived from using the electron probe method. This text then examines the various applications of backscattered electron and specimen current methods for quantitative analysis. Other chapters consider the fundamental concepts for quantitative electron probe microanalysis utilizing pure elements as standards. This book discusses as well the absolute method of quantitative chemical analysis by emission X-ray spectroscopy. The final chapter deals with the main advantage of the Kossel technique in the study of the thermodynamic and mechanical characteristics of crystals. This book is a valuable resource for scientists and research workers. Non-specialists who need information on this excellent analytical tool will also find this book useful.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of electron probe microanalysis of biological systems is to identify, localize, and quantify elements, mass, and water in cells and tissues. The method is based on the idea that all electrons and photons emerging from an electron beam irradiated specimen contain information on its structure and composition. In particular, energy spectroscopy of X-rays and electrons after interaction of the electron beam with the specimen is used for this purpose. However, the application of this method in biology and medicine has to overcome three specific problems: 1. The principle constituent of most cell samples is water. Since liquid water is not compatible with vacuum conditions in the electron microscope, specimens have to be prepared without disturbing the other components, in parti cular diffusible ions (elements). 2. Electron probe microanaly sis provides physical data on either dry specimens or fully hydrated, frozen specimens. This data usually has to be con verted into quantitative data meaningful to the cell biologist or physiologist. 3. Cells and tissues are not static but dynamic systems. Thus, for example, microanalysis of physiolo gical processes requires sampling techniques which are adapted to address specific biological or medical questions. During recent years, remarkable progress has been made to overcome these problems. Cryopreparation, image analysis, and electron energy loss spectroscopy are key areas which have solved some problems and offer promise for future improvements.

Download or read book Energy Dispersive X ray Analysis in the Electron Microscope written by DC Bell and published by Garland Science. This book was released on 2003-07-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth description of x-ray microanalysis in the electron microscope. It is sufficiently detailed to ensure that novices will understand the nuances of high-quality EDX analysis. Includes information about hardware design as well as the physics of x-ray generation, absorption and detection, and most post-detection data processing. Details on electron optics and electron probe formation allow the novice to make sensible adjustments to the electron microscope in order to set up a system which optimises analysis. It also helps the reader determine which microanalytical method is more suitable for their planned application.
Download or read book Practical Scanning Electron Microscopy written by Joseph Goldstein and published by Springer. This book was released on 1975-04 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the spring of 1963, a well-known research institute made a market survey to assess how many scanning electron microscopes might be sold in the United States. They predicted that three to five might be sold in the first year a commercial SEM was available, and that ten instruments would saturate the marketplace. In 1964, the Cambridge Instruments Stereoscan was introduced into the United States and, in the following decade, over 1200 scanning electron microscopes were sold in the U. S. alone, representing an investment conservatively estimated at $50,000- $100,000 each. Why were the market surveyers wrongil Perhaps because they asked the wrong persons, such as electron microscopists who were using the highly developed transmission electron microscopes of the day, with resolutions from 5-10 A. These scientists could see little application for a microscope that was useful for looking at surfaces with a resolution of only (then) about 200 A. Since that time, many scientists have learned to appreciate that information content in an image may be of more importance than resolution per se. The SEM, with its large depth of field and easily that often require little or no sample prepara interpreted images of samples tion for viewing, is capable of providing significant information about rough samples at magnifications ranging from 50 X to 100,000 X. This range overlaps considerably with the light microscope at the low end, and with the electron microscope at the high end.

Cl'!: '\ lEI( in 1949 has been developcd as an extremelv po\\'crful tool in spcctrochcmical analysis for a wide range of applications, ranging from qualitative elcmcntary distribution studies, to highly localiscd quantitatin analysis on a one micron scale. \\'ith the increasing number oi' versatile instruments, commcrcially available, the domain of applications - in metallurgy, solid state physics, mineralogy and geology, biology and medicine, arts and archeology - is rapidly expanding, particularly because reliable quantitative analyses can be achieved. It is well established that in multicomponent specimens, the relative x-ray intensity generated by the electron bombardment - i.e. the intensity ratio of the characteristic x-ray radiation emitted under identical experimental conditions by the specimen and a calibration standard - is not directly correlated to the elementary mass concentration. The use of a wide scale of carefully prepared homogeneous calibration standards is generally very tedious and restricted to binar)' systems. For more complex specimens, the conversion of recorded x-ra)' intensity ratios to elementary mass concentration requires, besides carefule selection of experimental conditions, an adequate correction calculation to take account oi' the various physical phenomenas occurring in the tarp;et - electron retardation, electron backseattering, x-ray excitation efficieney, fluorescence enhaneement by eharaeteristic and continuous radiation and x-ray mass absorption.
