“…Mass spectrometric studies are required to obtain data on the isotopic composition and concentration of Am (Chartier, Aubert, & Pilier, ; Aggarwal et al, ), speciation and vapor pressure of various Am species in the gas phase (Gotcu‐Freis et al, ), and stability constants of Am‐complexes present in the solution (Panak & Geist, ), to provide interesting gas phase chemistry studies (Gibson, ; Gibson & Marcalo, ). A brief description of each mass spectrometric technique is given below with particular reference to its application for analysis of Am and its compounds.…”

“…In view of the specification limit of 0.25 wt% of Am in Pu‐bearing nuclear fuels, 241 Am must be determined as a part of chemical quality assurance of nuclear fuels (Aggarwal et al, ). A number of radiometric techniques based on α‐ or γ‐spectrometry can be used for this purpose.…”

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.
