Determination of 90Sr at ultratrace levels in urine by ICP-MS

Abstract: Sr appears as a radionuclide in the decay series of nuclear fission and can therefore be found in nuclear waste or released by nuclear accidents. Current methods for the detection of this radionuclide are time consuming and may be prone to a large variety of interferents. In this work, inductively coupled plasma mass spectrometry is explored for the determination of 90 Sr in the presence of stable zirconium in urine. Specific techniques are investigated to remove this as well as other contributions to the back… Show more

“…This method gives an isotopic selectivity of 1.4×10 10 against stable strontium and a detection limit of 4 mBq. 90 Sr has also been determined by ICP-MS [36][37][38]70]. The main interference in the measurements of 90 Sr by ICP-MS is the isobar 90 Zr which has a natural abundance of 51%.…”

“…In spite of the improvements, detection limit reported for 90 Sr was still around 10 Bq/ml (equivalent to 2 pg/ml). Sector field ICP-MS has also been used for the determination of 90 Sr [37,38]. By using cold plasma and medium mass resolution, the Zr signal is significantly reduced, and a detection limit of 10 mBq/ml was achievable in a pure water sample.…”

“…Denaturing separation in the presence of SDS is shown to result in loss of iron ions which disappear even completely in the case of transferrin. The ratio of 56 Fe + to 32 S + proved a good measure for the determination of the iron load of the proteins.…”

“…Several analytical approaches exist to avoid such supplementary step and lower irradiation of operators. The double focusing Sector Field Inductively Coupled Plasma Mass Spectrometry (ICP-SFMS) is an effective tool which may provide a sufficiently high resolution for separating ions differing in mass by a fraction of a mass unit, as in the case of the 90 Zr/ 90 Sr isobaric interference (mass of 90 Zr = 89.9047 uma and 90 Sr = 89.9077 uma) [3,4]. But the required mass resolution (m/ m = 30,000), beyond actual possibilities, and the purchase price of such apparatus constitute a major obstacle which explains the development of others solutions.…”

“…But the required mass resolution (m/ m = 30,000), beyond actual possibilities, and the purchase price of such apparatus constitute a major obstacle which explains the development of others solutions. Cold plasma has been examined for taking advantage of the differences in ionization potential (IP(Zr) = 639.2 kJ mol −1 and IP(Sr) = 561.8 kJ mol −1 ) [3], but such plasma conditions enhance the formation of matrix-derivated polyatomic ions and sensitivity becomes particularly dependent on the matrix of the sample [5]. As a result, the use of ICP-MS with collision-reaction cells is increasingly widespread to avoid the chromatographic step and lower irradiation of operators.…”
