Quantitative Energy-dispersive Electron Probe X-ray Microanalysis of Individual Particles

An electron probe X-ray microanalysis (EPMA) technique using an energy-dispersive X-ray detector with an ultra-thin window, designated low-Z particle EPMA, has been developed. The low-Z particle EPMA allows the quantitative determination of concentrations of low-Z elements such as C, N, and O, as well as higher-Z elements that can be analyzed by conventional energydispersive EPMA. The quantitat...

scanning electron microscopy and energy-dispersive x-ray microanalysis of set cem cement after application of different bleaching agents

introduction: the present study evaluated the element distribution in completely set calcium-enriched mixture (cem) cement after application of 35% carbamide peroxide, 40% hydrogen peroxide and sodium perborate as commercial bleaching agents using an energy-dispersive x-ray microanalysis (edx) system. the surface structure was also observed using the scanning electron microscope (sem). methods ...

X-ray Microanalysis of Cultured Cells in the Scanning Electron Microscope and in the Scanning Transmission Electron Microscope: a Comparison

X-ray microanalysis of cultured cells as “whole mounts” (i.e., not sectioned) is used frequently e.g., to study mechanisms of ion transport. Cells can be cultured either on solid substrates or on thin plastic films on grids. Cells cultured on solid substrates are analyzed in the scanning electron microscope at relatively low accelerating voltage, cells cultured on thin films can be analyzed in ...
