Abstract
XRF was used for routine analysis of different kinds of alloys, such as archeological findings, materials used in dentistry, and Al alloyed with Ga used in industry. The results of these analyses are described in this paper.
Abstract
XRFS can be successfully used for routine on-line analysis of different agricultural products, for instance where food quality control is necessary. The optimization of the system for such purposes and the results obtained are shown on the example of the analysis of coffee.
Abstract
The use of X-ray tube fluorescence spectrometer with composite secondary target radiator is explained. Experimentally measured efficiencies and detection limits for coal samples are presented and discussed.
Abstract
The X-ray spectrometric method for uranium determination in sea water is discussed. Two techniques of uranium enrichment are presented: (1) precipitation with the chelating agent ammonium-1-pyrrolidine dithiocarbamate (APDC) in the presence of iron(II) as a carrier and (2) complexation with APDC followed by adsorption on activated carbon. The best pH range and the other optimized conditions for uranium determination in sea water with both methods are reported.
Abstract
A ring-shaped, 109 Bq241Am radioisotope source was used for the excitation of K-shell X-rays from rare earth elements (56<Z<64), present in powdered geological material. In order to improve the efficiency of the measurement of these elements in the concentration range down to 10 ppm, the optimum geometry of the system was found. The results obtained are presented and discussed.
