Title: A multiple ion counter total evaporation (MICTE) method for precise analysis of plutonium by thermal ionization mass spectrometry

Abstract

This study presents a total evaporation method for the analysis of sub-picogram quantities of Pu, utilizing an array of multiple ion counters. Data from three standards are presented to assess the utility of the technique. An external precision of 1.5% RSD (2σ) was achieved on aliquots approaching 100 fg for the minor 240Pu isotope. Accurate analysis of <1 femtogram of 240Pu, is achievable, with an external reproducibility of better than 10% RSD (2σ). Finally, this new technique represents a significant advance in the total evaporation method and will allow routine measurement of femtogram sized Pu samples by thermal ionization mass spectrometry.

  • The experiments involved in the PHENIX french nuclear reactor to obtain precise and accurate data on the total capture cross sections of the heavy isotopes and fission products require isotopic ratios measurements with uncertainty of a few per mil. These accurate isotopic ratio measurements are performed with mass spectrometer equipped with multi-collector system. The major difficulty for the analyses of these actinides and fission products is the low quantity of the initial powder enclosed in steel container (3 to 5 mg) and the very low quantities of products formed (several {mu}g) after irradiation. Specific analytical developments are performed by Thermalmore » Ionization Mass Spectrometry (TIMS) to be able to analyse several nanograms of elements with this technique. A specific method of acquisition named Total Flash Evaporation was adapted in this study in the case of lanthanide measurements for quantity deposited on the filament in the order of 2 ng and applied on irradiated fuel. To validate the analytical approach and discuss about the accuracy of the data, the isotopic ratios obtained by TIMS are compared with other mass spectrometric techniques such as Multiple-Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICPMS).

  • Investigations of the isotope fractionation behaviors of plutonium and uranium reference standards were conducted employing platinum and rhenium (Pt/Re) porous ion emitter (PIE) sources, a relatively new thermal ionization mass spectrometry (TIMS) ion source strategy. The suitability of commonly employed, empirically developed mass bias correction laws (i.e., the Linear, Power, and Russell's laws) for correcting such isotope ratio data was also determined. Corrected plutonium isotope ratio data, regardless of mass bias correction strategy, were statistically identical to that of the certificate, however, the process of isotope fractionation behavior of plutonium using the adopted experimental conditions was determined to be bestmore » described by the Power law. Finally, the fractionation behavior of uranium, using the analytical conditions described herein, is also most suitably modeled using the Power law, though Russell's and the Linear law for mass bias correction rendered results that were identical, within uncertainty, to the certificate value.« less
  • An internal standard technique which gives more than a 5-fold improvement in the precision of an isotopic analysis made in a thermal ionization mass spectrometer is described. The technique developed has application in the following fields: certain half life determinations; geochemical age determinations; nuclear absorption cross sections and low isotopic burnup; and isotopic dilution analysis for the assay of uranium. To apply the technique, three or more isotopes of an element must be present so that two different isotopic ratios of the same element can be compared in such a manner as to eliminate almost completely mass discrimination (instrument bias).more » The flexibility of the internal standard technique to problems which are amenable to surface ionization mass spectrometry is clarified is discussions given on its application to uranium isotope abundance measurements and to a new determination of the half life of Cs/sup 137/.

  • The mass spectrometric method is currently used for the determination of the molecular composition of vapors of both single compounds and 2-component systems. Overlapping of the mass spectra of the molecules contained in the vapor makes it difficult to determine quantitatively the partial pressures, if no data are available on the relative ionization cross sections of the nonvolatile compounds. A correlation was derived for the total evaporation isotherm of 2- component systems so that the dependence of the partial pressure on the composition of the condensate and the ionization cross sections of the molecules present in the vapor phase couldmore » be calculated. This supplements the method of using azeotropic mixtures with a known vapor-phase composition for the determination of the relative ionization cross section (A. W. Searcy et al. J. Chem. Phys. 32: 957(160) No. 3). The method was applied for the study of the NaF-- ZrF/sub 4/ system. The entalpies of dissociation of the NaZrF/sub 5/ and Na/sub 2/F/sub 2/ were found to be, by chemical reaction isobars, 62.2 plus or minus 4.6 and 54.9 plus or minus 2.2 kcal/mol, respectively.

  • The purpose of the present study existed in making a comparison between isotope dilution-thermal ionization mass spectrometry (ID-TIMS) and isotope dilution-secondary ion mass spectrometry (ID-SIMS) on the basis of their precision and accuracy. Three different sets of soils were therefore analyzed to determine their uranium and thorium contents. An analysis of variance (ANOVA) demonstrated that the precision of TIMS was about 6 times better than that of SIMS. It was clear in the case of TIMS that the overall precision can almost completely be explained by the variation in composition between samples, while for the SIMS analyses, the instrumental errormore » plays an important role in determining the precision. The overall SIMS/TIMS ratio for all data and for both elements equals 0.994 with a standard error of 0.004. As a result of this, it is statistically not fully proven that there is a systematic difference in accuracy between the two techniques. For the chemical separation of the analytes, a new element-specific resin was used and evaluated. The newer resin was able to remove metals such as iron, lead, and bismuth better than that traditional strong anion resin, but the uranium fraction obtained using the newer resin contained a larger amount of thorium. 14 refs., 7 figs., 4 tabs.« less
