We show the way to synthesize chalcopyrite glass for <italic>in situ</italic> sulfur isotope measurements using fsLA-MC-ICP-MS.
A new ideal zircon microanalytical reference material (Tanz) is presented for in situ U–Pb, O and Zr isotope measurements.
To expand the newly developed ARM glasses as reference materials for in situ microanalysis of isotope ratios and iron oxidation state by a variety techniques such SIMS, LA‐MC‐ICP‐MS EPMA, we report Li‐B‐Si‐O‐Mg‐Sr‐Nd‐Hf‐Pb data Fe 2+ /ΣFe these glasses. The were mainly obtained TIMS, MC‐ICP‐MS, IR‐MS wet‐chemistry colorimetric techniques. quality was cross‐checked comparing different or results from laboratories using same technique. All three appear to be homogeneous with respect...
Lead isotope ratio data were obtained with good precision and accuracy using a 266 nm femtosecond laser ablation ( fLA ) system connected to multi‐collector ICP ‐ MS MC through careful control of analytical procedures. The mass fractionation coefficient induced by was approximately 28% lower than that 193 excimer eLA helium carrier gas. exponential law correction method for Tl normalisation optimum adjusted utilised obtain Pb isotopic accuracy. ratios the glass reference materials NIST SRM...
Three zircon synthesis techniques (synthesis, high-temperature and high-pressure sintering fast hot-pressing sintering) for the preparation of reference materials Hf isotope analysis by LA-MC-ICP-MS were compared.
Abstract The Archaean Jiaodong Terrane is located in the southern segment of Palaeoproterozoic Jiao-Liao-Ji Belt, which separates Eastern Block North China Craton into Longgang and Langrim blocks. Controversy has long surrounded issue whether part or an exotic terrane. This study presents new zircon U–Pb ages for major lithologies Terrane, results indicate that terrane underwent two main magmatic events at ~2.89 Ga 2.62–2.56 metamorphic ~2.5 1.9–1.8 Ga. These are consistent with those other...
A new glass-making method was developed to allow the <italic>in situ</italic> analysis of trace elements and lead isotopes in rock samples.
The PAS-synthesized sphalerite has a homogeneous sulfur isotopic composition and is suitable to be matrix-matched reference material for in situ S isotope measurements of sphalerite.
A new matrix‐matched reference material (NWU‐Brt) with sulfur isotope ratios resembling those of natural barites has been developed for in situ S measurements by laser ablation multi‐collector inductively coupled plasma‐mass spectrometry (LA‐MC‐ICP‐MS). 100 g quantity barite crystal was milled to ultra‐fine particles and sintered a solid block using fast hot‐pressing sintering technique (FHPS). We report δ 34 determined ratio mass (IRMS), solution nebuliser (SN‐MC‐ICP‐MS) LA‐MC‐ICP‐MS,...
Because Pb isotopes can be used for tracing, they are widely in many disciplines. The detection and analysis of bulk samples usually conducted using thermal ionization mass spectrometer (TIMS) multiple-collector inductively coupled plasma (MC-ICP-MS), both which need external reference materials with known isotopic compositions to correct the discrimination effect produced during analysis. NIST NBS 981 is most material isotope analysis; however, reported by various analytical laboratories,...
A flux-free fusion technique using a boron nitride vessel and rapid acid digestion is presented for the determination of trace elements by ICP-MS.
A new natural chalcopyrite reference material TC1725 is prepared for in situ Cu isotope measurement by femtosecond laser ablation multi‐collector inductively coupled plasma‐mass spectrometry (fsLA‐MC‐ICP‐MS). Detailed textural examination and major element determination suggest the grains have no growth rim or zoning. The grain homogeneous with respect to isotopes based on a large number of measurements performed bulk solution nebuliser (SN)‐MC‐ICP‐MS, single‐grain SN‐MC‐ICP‐MS...
