| The investigation of illicit nuclear trafficking, nuclear safeguards and non-proliferation control, or nuclear fuel cycle studies requires sophisticated analytical methods to gain information such as isotope ′fingerprints′, age since last processing, fuel burn-up, and impurity signatures, to provide information on the origin of the material. A multi-collector TIMS was evaluated for the isotope ratio analysis of actinides. An analytical detection limit well below 100 attogram for 239–242+244Pu and 233+236U can be demonstrated with abundance sensitivities 106 − 108, employing resin bead load techniques on Re filaments. The utilizing of multi ion counters (MIC) will be discussed, as well as analyzing two or more analytes in the same run, e.g. combined U − Pu samples. We have investigated the capabilities of a time-of-flight ICP-MS for the analysis of elemental signatures in uranium matrices. Application of multi-variate statistical methods to elemental and isotopic data for discrimination of samples will be discussed. |
