Progress in laboratory grazing emission x-ray fluorescence spectrometry
X-Ray Spectrometry, 1999Recently, grazing emission x-ray fluorescence (GEXRF) spectrometry, also referred to as grazing exit spectrometry, attained a special position in the field of XRF. The technique exploits the advantages of the total-reflection phenomenon as is done in the related total-reflection XRF technique.

Ecological Indicators, 2019
Ecological risk assessment of soil is commonly performed by determining heavy metals (HMs) through conventional laboratory analysis, which is cost-, time- and labor-consuming, especially in large-scale agricultural soils.

Rotating Sample Holder for X-Ray Emission Spectrometry
Applied Spectroscopy, 1969A rotating sample holder is invaluable in x-ray emission analysis of nonhomogeneous samples because when such samples are rotated,1,2 different sample areas are observed continuously, thus permitting an averaging of irregularities. This feature of the sample holder is of significance in the nondestructive testing of materials in that it provides more ...

Innovations in X-Ray Induced Electron Emission Spectrometry (XIEES)
Key Engineering Materials, 2010In 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.

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, 1987Abstract 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, 1990Abstract: 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, 2019Portable 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.
