Determination of silicon in organic matrices with grazing-emission X-ray fluorescence spectrometry
Spectrochimica Acta Part B: Atomic Spectroscopy, 1999Abstract The potential of a prototype grazing-emission X-ray fluorescence spectrometer for reliable analysis of sample solutions, obtained by pressurized microwave oven digestion of Si-spiked organic and biological materials, was investigated as part of an inter-laboratory study.

X-Ray Secondary-Emission (Fluorescence) Spectrometry; General Introduction
1975Having considered the excitation, nature, and properties of x-rays and x-ray spectra, we now begin our study of the application of x-ray spectra to chemical analysis. However, first we define some terms used throughout the book.

Proton-induced X-ray emission (PIXE) spectrometry — state of the art
Fresenius' Zeitschrift für analytische Chemie, 1986The development of the PIXE method for multielemental analysis is described. A brief account is given of the physical principles and the experimental arrangements. The use of PIXE is illustrated by a number of typical applications in geology, biology, medicine and environmental research.

Application of X-ray emission spectrometry to the estimation of the heavy elements (at. no. 79–83)
Microchemical Journal, 1963Abstract A study with the X-ray spectrometer of the conditions required for the estimation of microgram quantities of the elements gold, mercury, thallium, lead, and bismuth is described. Scanning of the range from 26 ° to 38 °C (2θ) permits the resolution of the L α and L β lines of these elements.

Influence of irradiation time on the usability of briquetted samples in X-ray emission spectrometry
Fresenius' Zeitschrift für Analytische Chemie, 1985The influence of X-ray radiation on samples of organic binders (starch, graphite and cellulose) and briquetted samples of sinter and sinter mixture of blast furnace charge was examined. The time of irradiation by the primary X-ray beam was from 0 to 300 min.

Detectors for spectrometry of the X-ray emission from germanium obtained by the hydride method
Soviet Atomic Energy, 1985This paper investigates certain characteristics of p-n structures, prepared on a base of germanium obtained by the hydride method. The purpose of the study is to estimate the degree of purity of the germanium and its applicability for the preparation of the detectors with a high energy resolution. Monocrysstals of the p type were used. On completion of

A new procedure of powdered sample preparation by melting for x‐ray emission spectrometry
X-Ray Spectrometry, 1983Abstract A new procedure of powder sample preparation for x‐ray emission analysis by melting has been worked out in detail. The mixture sample‐flux was melted and cooled in graphite crucible. The resulting glass disk was ready for direct measurement.

Radiation effect on the binder of briquetted samples in x-Ray emission spectrometry
1998In this paper the behaviour of boric acid as binder was investigated. On basis of debyegrams and secondary electron micrographs radiolytic changes of boric acid were proved. Debyegrams of sample of boric acid showed that spottiness and prefered orientation were enhanced after exposure of sample to x-Rays.
