On the actinide mass range the performances observed are characterized by high sensitivity, around 2.8·106 cps·µg−1·l, and low background, below 0.3 cps. Therefore, the absolute instrumental detection limit is approximately 0.05 fg for Pu isotopes. Furthermore, the 235U/238U ratio for a 0.5 µg·l−1 U500 isotopic standard could now be measured using the ICP-SFMS with a relative standard deviation less than 0.1%. Moreover, the accuracy of the measured ratio was demonstrated at low concentration with the target value remaining within experimental uncertainty limits.", pages = "609-617(9)", url = "http://www.ingentaconnect.com/content/klu/jrnc/2004/00000261/00000003/05380077" doi = "doi:10.1023/B:JRNC.0000037103.25378.42" }
