A new multi-isotopic plutonium standard for isotopic ratio measurements with AMS was created by mixing different single-isotope IRMM standards (Pu-239, Pu-240, Pu-242, Pu-244). This standard material has been measured at the AMS facilities at Canberra (Australia), Cologne (Germany), Caserta (Italy), Sevilla (Spain) and Zurich (Switzerland). Aditionally, the material was characterized using a Neptune MC-ICPMS (multi-collector inductively coupled plasma mass spectrometry) at the joint Cologne-Bonn facility and with RIMS (resonant ionisation mass spectrometry) at the University of Mainz (Germany). Consensus values for the standard material will be proposed.
