Innovations in X-Ray Induced Electron Emission Spectrometry (XIEES)

Key Engineering Materials, 2010
In modern sciences and technologies it is required to investigate local atomic and electron structure of matter independently on its aggregate state. There are advanced methods aimed at short order. These methods are based on the phenomena accompanied by interference of secondary electrons excited by primary X-ray radiation.

High‐resolution x‐ray emission spectrometry in the lithium K range with a reflection zone plate spectrometer

X-Ray Spectrometry
Implementing a newly developed spectrometer for the soft x‐ray range of (35–130) eV based on reflection zone plates was successfully accomplished on an electron probe microanalyzer. In this context, we present the first spectra acquired using this setup,

Importance of sample grinding time in X‐ray emission spectrometry

X-Ray Spectrometry, 1987
Abstract The effect of the sample grinding time on X‐ray spectrometric results was examined on real samples (limonite iron ore, sinter mixture and blast furnace slag). Comparative results were obtained for X‐ray diffraction analysis and scanning electron microscopic analysis.

Determination of selenium in blood components by X-ray emission spectrometry

Biological Trace Element Research, 1990
Abstract: Sampling, storing, sample pretreatment, and experimental conditions for selenium (Se) determination in human serum, plasma, and whole blood by X-ray emission spectrometric (XRS) methods are described. Concentration levels in these biological fluids, found by this technique, are discussed and compared to values found by other techniques for ...

Advances in Tropical Soil Characterization via Portable X-Ray Fluorescence Spectrometry

Pedosphere, 2019
Portable X-ray fluorescence (pXRF) spectrometers can be used to determine the elemental composition easily, rapidly, and without using chemical reagents, which is very important for tropical regions due to the lack of detailed soil characterization data.

The Determination of Oxides of Sulfur by X-Ray Emission Spectrometry

American Industrial Hygiene Association Journal, 1968
Abstract Determination of sulfur dioxide, sulfur trioxide, or sulfuric acid mist becomes difficult in the presence of other acid gases or where collected samples are highly colored or turbid. A method is described by which all oxides of sulfur are oxidized and precipitated as barium sulfate.

Determination of Catalyst Residues in Polyolefins by X-Ray Emission Spectrometry.

Analytical Chemistry, 1962
AbstractX-ray fluorescence methods for the direct determination of aluminum, chlorine, titanium, and iron in polyolefins have been developed. The procedures require no preconccntration of elements, are satisfactory for any polyolefin, and are free from matrix effects.

Analysis of metal-laden water via portable X-ray fluorescence spectrometry

Journal of Hydrology, 2018
A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption spectrometry (FAAS), atomic ...

Applications of wavelenght-dispersive spectrometry in particle-induced X-ray emission analysis

Nuclear Instruments and Methods, 1977
Abstract The high-resolution cpabilities of wavelenght-dispersive spectrometry can be profitably employed in the analysis of materials containing elements which cannot be early resolved by Si(Li) spectrometers. This situation frequently arises in cases where the concentration of an element must be determined in the presence of large quanities of ...

Analysis of phospholipids by thin-layer chromatography and X-ray emission spectrometry

Journal of Chromatography A, 1972
The use of X-ray emission spectrometry for in situ quantitative analysis of phospholipids after separation by two-dimensional thin-layer chromatography is described. With this procedure, microgram quantities of phospholipids can be analyzed.
