Description
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 0.01 ppt and 0.006 ppt 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 x 10-9 and for 240Pu/239Pu the isotope ratio is 0.17. (orig.)
