Ion distribution in roots of barley seedlings measured by electron probe x-ray microanalysis.
The distribution of ions, particularly K and Na, was studied in roots of barley seedlings grown on various ionic solutions. Analyses were made by means of electron probe x-ray microanalysis using frozen, fractured bulk specimens. By this technique, it was demonstrated that there can be variability in the ratio K/Na measured in the vacuoles of cortical cells, with this ratio often being lower in...
متن کاملCharacterization 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...
متن کاملDistribution analysis of epoxy groups in polymers by derivatization-electron probe X-ray microanalysis.
An analytical method, referred to as "derivatization-electron probe X-ray micro-analysis (XMA)", has been developed to determine the distribution of a small amount of the functional groups in a polymer. The suitable conditions for the derivatization reaction with epoxy groups, which contribute to the hardening reactions of polymers, were investigated. It was found that epoxy groups in polymers ...
متن کاملMeasurement of total calcium in neurons by electron probe X-ray microanalysis.
In this article the tools, techniques, and instruments appropriate for quantitative measurements of intracellular elemental content using the technique known as electron probe microanalysis (EPMA) are described. Intramitochondrial calcium is a particular focus because of the critical role that mitochondrial calcium overload plays in neurodegenerative diseases. The method is based on the analysi...
متن کاملChanges in elemental content during apoptotic cell death studied by electron probe X-ray microanalysis.
Recent data suggest that changes in ionic content, primarily potassium, play a pivotal role in the progression of apoptosis. However, the changes in total element content, i.e., sodium (Na), magnesium (Mg), phosphorous (P), chlorine (Cl), potassium (K), and calcium (Ca), during apoptosis have not been evaluated. Electron probe X-ray microanalysis (EPXMA) was used to measure total element conten...
