While the former has been used for long time, the latter is rather new in the field of speciation. These two techniques have different advantages such as sensitivity (especially for TRLIF), selectivity and multielement capabilities (in case of ES-MS). Examples obtained from studies carried out within the CEA are presented. Concerning TRLIF, emphasis is put on uranyl ion speciation in nitric acid to phosphoric acid going through hydroxo complexes. Concerning ES-MS, humic substances identification as well as speciation of cesium, zirconium, thorium and uranyl ions in various complexing media are presented. Comparisons of TRLIF and ES-MS results are made in the case of uranyl hydroxo complexes and favourably compared with OECD data. Trends for these two techniques are also discussed. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/11/2003(2003-11-01), 651-658 0033-8230 91:11/2003<651 2003 91 ract https://doi.org/10.1524/ract.91.11.651.23467 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.91.11.651.23467 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Moulin Christophe NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/11/2003(2003-11-01), 651-658 0033-8230 91:11/2003<651 2003 91 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
