I. Helal, N. F. Zahran, M. A. Amr, A. M. Abd El-Lateef, I. I. Bashter, H. T. Mohsen, Y. Abbas] Extensive work is under way using High Resolution-ICP-MS for 90Sr, 234U, 235U, 238U, 239Pu, 240Pu, and 241Am detection. Sample preparation procedures based on liquid-liquid extraction and ion exchange chromatography were developed. Sr, U, Pu, and Am were separated from their matrix and concentrated to improve the power of detection in the mass spectrometer. A microconcentric nebulizer with a desolvation introduction system (Ardius) is used. Instrumental limits of detection using Sr and U standard solutions are 0.01ppt and 0.006ppt for Sr and U, respectively. A study is presented on the mass interferences for the specified radionuclides. In the environmental samples investigated the 90Sr/86Sr isotope ratio is 6.02×10-9 and for 240Pu/239Pu the isotope ratio is 0.17. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Helal A.
