A high throughput Rb-Sr dating method using solution tandem ICP-MS/MS (87Sr/86Sr) and standard addition calibration ICP-MS (Rb/Sr)

O método de datação química U-Th-Pb (não-isotópica) de monazita por microssonda eletrônica vem sendo desenvolvido há pelomenos 20 anos e já tem o reconhecimento da comunidade geológica por apresentar resultados que se equivalem à geocronologia isotópicaU-Pb. Este mineral contém quantidades negligenciáveis de chumbo comum, guardando apenas Pb radiogênico proveniente do Th e U destemineral. O desenvolvimento deste método no Laboratório de Microanálises do Departamento de Física da Universidade Federal de MinasGerais mostra que os dados químicos de U, Th e Pb de cristais de monazita fornecidos por sua microssonda eletrônica produzem idadesnão-isotópicas para eles que se equiparam às idades isotópicas U-Pb produzidas pela técnica LA-ICP-MS. Grãos de monazita de placersmarinhos de Buena (RJ) isotopicamente datados pelo método U-Pb com idades entre 530 e 580 Ma foram quimicamente datadas na UFMGentre 505 e 580 Ma. Estes resultados são consideravelmente compatíveis e colocam o referido laboratório a disposição da comunidadegeocientífica para obtenção de idades de cristais de monazita.Palavras-Chave: MONAZITA, DATAÇÃO QUÍMICA, MICROSSONDA ELETRÔNICA, UFMG ABSTRACTDEVELOPMENT OF THE MONAZITE U-Th-Pb CHEMICAL DATING METHOD BY USING ELECTRON MICROPROBE AT UFMG. Themonazite U-Th-Pb chemical dating method (non-isotopic) by electron microprobe has been developed for about 20 years and has theacceptance of the geological community by presenting results that are equivalent to the isotope U-Pb geochronology. This mineral containsnegligible amounts of common lead, keeping only radiogenic Pb from the Th and U of this mineral. The development of this method in themicroanalysis laboratory of the Physics Department- UFMG shows that the monazite U, Th and Pb chemical data provided by itsmicroprobe produce non-isotopic ages for it that are similar to the U-Pb isotopic ages produced by LA-ICP-MS technique. Monazite grainsfrom marine placers of Buena (RJ) isotopically dated by method U-Pb between 530 and 580 Ma were chemically dated at UFMG between505 and 580 Ma. These results are consistent each other and put the laboratory available to the geoscience community as a tool inobtaining monazite ages.Keywords: MONAZITE, CHEMICAL DATING, ELECTRON MICROPROBE, UFMG

Plasma Mass Spectrometry

A method for mercury high throughput rapid speciation analysis was built by short column capillary electrophoresis (SC-CE) coupled with inductively coupled plasma mass spectrometry (ICP-MS). A micromist nebulizer was employed to increase the nebulization efficiency and a laboratory-made removable SC-CE-ICP-MS interface on the basis of cross design was applied to alleviate buffer contamination of ICP-MS. In less than 60 s methylmercury (MeHg(I)) and inorganic mercury (Hg(II)) were separated in a 16 × 75 μm i.d. short column fused-silica capillary at 21 kV, while a mixture of 30 mmol/L boric aicd + 5% (v/v) CH3OH (pH=8.60) acted as running electrolyte. The precisions (RSD, n=5) of migration time and peak area for MeHg(I) and Hg(II) were in the range of 1.4-2.6% and 3.3-3.4%, respectively. The limits of detection (3σ) mercury species were 9.7 and 12.0 μg/L, respectively. The recoveries for Hg(II) MeHg(I) were in the range of 96-107% and 99-105%.

The Matrix

Abstract A method has been developed for quantification of trace rare earth (Ce, Dy, Er, Eu, Gd, Ho, La, Nd, Pr, Sm, Tb and Yb) impurities in alumina and aluminum by inductively coupled plasma mass spectrometry (ICP-MS) after matrix separation. The matrix separation was achieved by selective precipitation of trace elements. Due to its refractory nature a microwave digestion method was developed and optimized for the quantitative dissolution of Al2O3. The analytical methodology was validated by recovery studies with standard addition as well as with an independent γ-spectrometry technique using 152,154Eu tracers. The observed recovery in the synthetic samples was in the range of 93–100% with precision within 6.1–11.6 (%RSD), while the same in the case of radio tracer technique were found to be >98% and <2% (RSD), respectively. The method detection limit was found within 0.5–8.3 μg kg−1, respectively. The procedure is simple, organic waste free and suitable for routine analysis.
