“…Due to the physical principles of this machine, a rather high mass fractionation is observed (~0.7%/amu). Use of thallium (Tl), an element of similar mass, as an internal standard (Longrich et al, 1987) provides an opportunity for correction of mass dependency of the instrumental bias. Despite the fact that the fractionation coefficients are not strictly identical for Tl and Pb, the ratio of these coefficients remains constant for a given analytical session (White et al, 2000).…”

Even after its being phased out in gasoline in the late 90's, lead (Pb) is still present at relatively high levels in the atmosphere of Beijing, China (0.10-0.18 μg.m -3 ). Its origin is subject to debate as several distinct sources may contribute to the observed pollution levels. This study proposes to constrain the origin(s) of Pb and strontium (Sr) in aerosols, by coupling both Pb and Sr isotope systematics. The characterisation of the main pollution sources (road traffic, smelters, metal refining plants, coal combustion, cement factories, and soil erosion) shows that they can unambiguously be discriminated by the multi-isotope approach ( 206 Pb/ 204 Pb and 87 Sr/ 86 Sr). The study of total suspended particulates (TSP) and fine particles (PM 2.5 ) from Beijing and its vicinity indicates that both size fractions are controlled by the same sources. Lead isotopes indicate that metal refining plants are the major source of atmospheric lead, followed by thermal power stations and other coal combustion processes. The role of this latter source is confirmed by the study of strontium isotopes. Occasionally, emissions from cement plants and/or input from soil alteration are isotopically detectable.

“…The mass bias factor, β, can be estimated from the following equation: analysis number analysis number Longerich et al (1987) for Pb isotope measurement, and it was extended to other elements. This correction assumes that the mass fractionation factor is equal between the target element and doped element (in our case, Sn and Sb, respectively).…”

“…Instrumental mass bias is significant in ICP-MS analyses and must therefore be carefully determined and corrected. For ICP-MS, heavier isotopes have a better transmission efficiency through the plasma-vacuum interface region, and so isotopic ratios are biased to the heavy isotopes [32].…”

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.
