Electron Microprobe Analysis and Scanning Electron Microscopy in Geology

Abstract

Originally published in 2005, this book covers the closely related techniques of electron microprobe analysis (EMPA) and scanning electron microscopy (SEM) specifically from a geological viewpoint. Topics discussed include: principles of electron-target interactions, electron beam instrumentation, X-ray spectrometry, general principles of SEM image formation, production of X-ray 'maps' showing elemental distributions, procedures for qualitative and quantitative X-ray analysis (both energy-dispersive and wavelength-dispersive), the use of both 'true' electron microprobes and SEMs fitted with X-ray spectrometers, and practical matters such as sample preparation and treatment of results. Throughout, there is an emphasis on geological aspects not mentioned in similar books aimed at a more general readership. The book avoids unnecessary technical detail in order to be easily accessible, and forms a comprehensive text on EMPA and SEM for geological postgraduate and postdoctoral researchers, as well as those working in industrial laboratories.

Long-term exposure to elevated pCO2 more than warming modifies early-life shell growth in a temperate gastropod

“…Images of each crosssection were taken for further analysis at appropriate magnification to determine crystal polymorph structure (Marxen et al, 2008). The elemental ratio from each x-ray spectrum was recorded (for technique see Reed, 2005).…”

Color electron microprobe cathodoluminescence of Bishunpur meteorite compared with the traditional optical microscopy method

“…It is outside the scope of this work to discuss the reasons of color in minerals because its origin has been investigated for a long time. Despite the fact that color in minerals is caused by either crystal-structure defects or trace elements (Reed, 2005), there are several mechanisms that can contribute to the coloring of gems (Fritsch and Rossman, 1987); thus, in most of the cases, it is very difficult to set a reason for the color emitted by these materials.…”

Candida parapsilosis complex water isolates from a haemodialysis unit: biofilm production and in vitro evaluation of the use of clinical antifungals

“…To determine the effect of antifungal drugs on the morphology and architecture of Candida biofilms, they were prepared according to a previously published protocol (Reed 1996). Briefly, Candida biofilms were formed on sterile polyvinylchloride (PVC) disks within 12-well cell culture plates (Corning) by dispensing cell suspensions containing 5.0 x 10 6 cells/mL in RPMI 1640 onto appropriate disks at 37ºC.…”
