“…The ICP-QMS, the first X series modified with ion source and placed in a glove box to work with radioactive samples, was previously described [23]. Sample introduction into the plasma was made via a quartz peltier-cooled impact bead spray chamber and a quartz concentric nebulizer (1.0 mL/min).…”

46The French Atomic Energy Commission has carried out several experiments including the 47 mini-INCA (INcineration of Actinides) project for the study of minor-actinide transmutation 48 processes in high intensity thermal neutron fluxes, in view of proposing solutions to reduce 49 the radiotoxicity of long-lived nuclear wastes. In this context, a Cm sample enriched in 248 Cm 50 (~97 %) was irradiated in thermal neutron flux at the High Flux Reactor (HFR) of the Laue-51Langevin Institute (ILL). This work describes a quadrupole ICP-MS (ICP-QMS) analytical 52 procedure for precise and accurate isotopic composition determination of Cm before sample 53 irradiation and of Cm and Cf after sample irradiation. The factors that affect the accuracy and 54 reproducibility of isotopic ratio measurements by ICP-QMS, such as peak centre correction, 55 detector dead time, mass bias, abundance sensitivity and hydrides formation, instrumental 56 background, and memory blank were carefully evaluated and corrected. Uncertainties of the 57 isotopic ratios, taking into account internal precision of isotope ratio measurements, peak 58 tailing, and hydrides formations ranged from 0.3% to 1.3%. This uncertainties range is quite 59 acceptable for the nuclear data to be used in transmutation studies.

“…The first spectrometer was used for the analytical development process and for the second one a glove box was added around the source to analyze irradiated samples [17]. In both cases, the samples were introduced into the plasma via a quartz concentric nebulizer (1.0 mL min -1 ) and a quartz Peltier-cooled impact bead spray chamber.…”

A methodology to purify a 166m Ho solution has been developed by a combination of activity and mass concentration measurements in order to further determine the 166m Ho half-life. The isobaric interference at m/q^166 requires Ho purification from non-natural Er with a high purification degree due to the large amount of Ho as opposed to Er. The Ho/Er separation was achieved using high-performance liquid chromatography on a semi-preparative column followed by purification on gravitational chromatography. The efficiency of the separation was evaluated after precise determination of the Er isotopic composition. The purification methodology enabled to separate Ho from Er.

677 1 Currently, inductively coupled plasma mass spec trometry (ICP MS) is one of the leading methods for the determination of the elemental composition of various objects [1][2][3][4][5][6]. ICP MS reveals such unique characteristics as the possibility to perform simulta neous multielemental analysis, high sensitivity, broad dynamic range, high signal stability, and not least important-high productivity. One of the main prob lems in ICP MS is spectral interferences, arising from the formation in plasma of many ions of argon, hydro gen, oxygen and other sample components as well as doubly and triple charged ions. While in plasma, or passing through interface, these ions undergo plasma chemical reactions to form polyatomic ions with almost the same mass as one of the element's isotope being determined. The spectral resolution of quadru pole mass analyzer as well as the resolution of double focusing mass spectrometer is not always sufficient to separate those ions. As a result, the signals of analyte ion and the interfering molecular ion are represented in mass spectrum as a single peak.Spectral interferences in ICP MS can be ranged as follows:1) isobaric interferences caused by the overlapping of the signals of isotopic ions of different elements, having almost the same mass;2) overlaps from doubly charged ions; 3) polyatomic overlaps arising from the formation in plasma of ions, containing more than one atom.The example of isobaric interference is the overlap of 40 Аr and 87 Sr on 40 Ca and 87 Rb respectively. In most cases isobaric interferences do not create a problem, because for virtually any element, except for artificial and enriched isotopes, it is possible to choose an iso tope that is free from an isobaric overlap. Besides, iso 1 The article was translated by the authors. baric interferences can be accounted for using simple mathematic correction equations, considering the known natural abundance of isotopes [5,7,8]. Dou bly charged ion overlaps, for example 138 Ва 2+ / 69 Ga + , very rarely create a problem and, as a rule, are of rela tively low intensity because the second ionization potentials of most elements are quite high. Doubly charged ion overlaps can be suppressed by the correct tuning of spectrometer and can be accounted for using mathematic correction.The most part of publications is dedicated to poly atomic interferences. Several hundreds of possible polyatomic ions are described in literature [7⎯9]. The informative review (168 references) in Russian on polyatomic spectral interferences is presented in [8]. When analyzing aqueous solutions, the most abundant ions in plasma are the ones containing oxygen atoms-oxides (MeO + , ArO + ), argon atoms-argides (Ar 2 + , MeAr + ), and their combinations with the inclu sion of other atoms, for example, hydrogen-hydrox ides (H n O + , ArOH + , MeOH + ), hydrides (ArH + , MeH + ) etc. It is obvious that depending on the com position and the concentration of elements in a sam ple and the tuning parameters of spectrometer (for ward power, sampling depth ...
