“…Accelerator mass spectrometry (AMS) is currently the only technique that is able to determine naturally occurring 236 U/ 238 U ratios down to the 10 À12 level (or even below) with sufficient efficiency (e.g. Zhao et al, 1994;Fifield, 2008a;Steier et al, 2010).…”

“…Recent developments of accelerator mass spectrometry (AMS) methods for analysis of long-lived natural and anthropogenic radionuclides at ultra low-levels have opened doors for oceanic investigations which were not possible before either because of a lack of sensitivity, or availability of suitable samples [1][2][3]. Together with recent developments in the radiometrics sector, especially those using underground environment for analysis of medium and short lived radionuclides, we have at disposal necessary techniques which can be used for tracing radionuclides in the marine environment [3][4][5].…”

“…AMS, also known as high‐energy mass spectrometry, offers high efficiency, high rejection of interferences, low susceptibility to matrix components, and large dynamic range to determine heavy radioactive isotopes (Litherland, ; Vogel et al, ; Fifield, ). AMS generates negative ions by Cs sputtering of the target that contains the element of interest.…”

The manuscript reviews the various mass spectrometric techniques for analysis and chemical studies of Americium. These methods include thermal ionization mass spectrometry (TIMS), and inductively coupled plasma source mass spectrometry (ICPMS) for the determination of Am isotope ratios and concentration in nuclear fuel samples of interest in nuclear technology, and in complex biological and environmental samples. Ultra-sensitive mass spectrometric techniques of resonance-ionization mass spectrometry (RIMS), and accelerator-based mass spectrometry (AMS) are also discussed. The novel applications of electrospray ionization mass spectrometry (ESIMS) to understand the solution chemistry of Am and other actinides are presented. These studies are important in view of the world-wide efforts to develop novel complexing agents to separate lanthanides and minor actinides (Am, Np, and Cm) for partitioning and transmutation of minor actinides from the point of view of nuclear waste management. These mass spectrometry experiments are also of great interest to examine the covalent character of actinides with increasing atomic number. Studies on gas-phase chemistry of Am and its oxides with Knudsen effusion mass spectrometry (KEMS), Fourier-transform ion cyclotron resonance mass spectrometry (FTICR-MS), and laser-based experiments with reflectron time-of-flight mass spectrometer (R-ToF) are highlighted. These studies are important to understand the fundamental chemistry of 5f electrons in actinides. Requirement of certified isotopic reference materials of Am to improve the accuracy of experimental nuclear data (e.g., the half-life of Am) is emphasized. © 2016 Wiley Periodicals, Inc.
