X-ray microanalyses in the variable pressure (environmental) scanning electron microscope

X-Ray Microanalysis in the Variable Pressure (Environmental) Scanning Electron Microscope

Electron-excited x-ray microanalysis performed in the variable pressure and environmental scanning electron microscopes is subject to additional artifacts beyond those encountered in the conventional scanning electron microscope. Gas scattering leads to direct contributions to the spectrum from the environmental gas, as well as remote generation of x rays by electrons scattered out of the focus...

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 ...

the scanning electron microscope

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

Identification of Mast Cells in the Scanning Electron Microscope by Means of X-ray Spectrometry

In mixed populations of rat peritoneal fluid cells, the mast cells can be differentiated from other cell types in the scanning electron microscope by virtue of the X-ray emission referable to their sulfur content. Both stationary probe and X-ray mapping are feasible; the amount of sulfur eliciting a signal is estimated to be about 8 x 10(-18) g.
