Th-U-Pu-Cm-Am isotopic composition of low-level samples using plasma source mass spectroscopy
- Lawrence Livermore National Lab., CA (United States)
Plasma source mass spectroscopy (ICP-MS) has a significant role in many fields linking high precision and accuracy inorganic mass spectroscopy and bulk element analyses. This paper describes application of ICP-MS techniques to isotopic measurement of actinides and transuranic elements in environmental samples. These samples encompass hydrologic and saline waters, soils and sediments that typically have very low heavy element abundances. The goal is to measure accurately isotopic composition and abundance of rare elements in diverse matrices. The methodology for isotope ratio and isotope dilution measurement requires more instrument set-up and calibration than bulk element determination. ICP-MS techniques are nebulization and enhanced sensitivity for sub-picogram abundances using novel electro-thermal vaporization. Clean room sample preparation is critical.
