X-ray microanalysis of electron-dense bodies inCladosporium resinae

X-ray microanalysis attachment for electron microscope.

Characterization of atmospheric particles by electron probe X-ray microanalysis.

Microchemical glass standards were used to validate a quantitation method based on peak-to-background (P/B) ratios from electron probe x-ray microanalysis spectra. This standardless method was applied to the determination of concentrations of individual particles from Malpha or Lalpha lines, as well as from Kalpha lines. The algorithm was tested on particulate glass samples for diameters rangin...

Electron probe microanalysis of the dense bodies of human blood platelets.

Under the electron microscope various substructures were observable in the attenuated cytoplasm of platelets without any treatment, i.e., fixation, embedding or staining. The granulomere of platelets revealed dense bodies of 200-300nm diameter and smaller dense granules (about 50nm). Larger ovoid bodies with dense granules presumably corresponded to mitochondria and lysosomes. In the hyalomere ...

Electron probe X-ray microanalysis of cultured epithelial tumour cells with scanning electron microscopy.

Three methods have been used to prepare cultured cells for electron probe X-ray microanalysis (EPXMA): (1) analysis at the subcellular level of freeze-dried ultrathin cryosections with scanning transmission electron microscopy (STEM); (2) analysis at the cellular level of whole freeze-dried cells with STEM; and (3) analysis at the cellular level of whole freeze-dried cells with scanning electro...

X-Ray microanalysis of stratified specimens

This paper presents a description of the state of the art methodology and software for the application of x-ray microanalysis to thin surface layers and more generally to the characterization of stratified specimens. The sensitivity of the technique to near-surface segregation is demonstrated. Some emphasis is given on the eS(pz) function (the distribution in depth of the primary generated x-ra...
