Electron Probe Microanalysis (EPMA)
An electron microprobe is an electron microscope designed for the non-destructive x-ray microanalysis and imaging of solid materials. It is essentially a hybrid instrument combining the capabilities of both the scanning electron microscope (SEM) and an x-ray fluorescence spectrometer (XRF), with the added features of fine-spot focusing (~ 1 micrometer), optical microscope imaging, and precision...
متن کاملElectron Probe Microanalysis
The section on tranquilizers comprises three chapters: (1) Phenothiazine derivatives by P. B. Bradley, (2) Rauwolfia derivatives by J. J. Lewis and (3) Diphenylmethane derivatives by T. R. Sherrod. The first two are, quite justifiably, restricted to detailed accounts of the pharmacology of chlorpromazine and reserpine respectively, which are treated as model compounds representative of their ch...
متن کاملQuantitative Electron Probe Microanalysis
The recognition and understanding of the role of the microstructure in controlling the macroscopic behavior of a material has been a major theme of science and technology throughout the history of NBS/NIST. In materials science, the late 19th century saw the development of the sample preparation procedures we know today as “metallography” and “materialography,” and the emergence of optical micr...
متن کاملUncertainty in Quantitative Electron Probe Microanalysis
Quantitative electron probe analysis is based on models based on the physics or x-ray generation, empirically adjusted to the analyses of specimens of known composition. Their accuracy can be estimated by applying them to a set of specimens of presumably well-known composition.
