“…Proteus demonstrated the ability to accurately Rb/Sr date in situ samples down to a 2SD precision of 4‰. 41 In situ analysis of Ti isotopes was also conducted to produce ε 46 Ti and ε 50 Ti isotope maps used to identify anomalous presolar grains in a CM2 chondrite. This was achieved using O 2 as a reaction gas to reduce the isobaric interferences of Ca, V, and Cr by >95% through the measurement of TiO + .…”

“…The method used for in situ Rb/Sr analysis was based on that which had been previously reported for Proteus. 41 The analysis required the use of SF 6 as a reaction gas. It was introduced as the pure gas (99.999% purity, Linde) to the cell via one MFC and mixed with He via the other MFC.…”

“…The internally normalized 87 Sr/ 86 Sr ratios were then externally normalized to a Telica feldspar plagioclase standard with a known 87 Sr/ 86 Sr of 0.704000 ± 0.000005. 41 A sample taken from Shap granites (SG-1), which had been analyzed previously on Proteus, was chosen to be dated on Vienna. It and the secondary standard DG-1 both contained euhedral K-feldspar megacrysts (>1 cm) in a matrix of plagioclase, biotite, quartz, and accessory phases such as apatite.…”

Project Vienna: A Novel Precell Mass Filter for Collision/Reaction Cell MC-ICPMS/MS

The last decade has seen widespread adoption of triple quadrupole-based inductively coupled plasma−tandem mass spectrometry (ICPMS/MS) technique using a collision/reaction cell in combination with a precell bandpass mass analyzer to measure isotopes otherwise masked by spectral interferences. High-precision isotope ratio analysis containing such isotopes would benefit from a similar capability on a multicollector inductively coupled plasma mass spectrometry (MC-ICPMS) platform, but using a quadrupole-based precell mass analyzer for MC-ICPMS/MS has several limitations. To overcome these limitations, we developed a novel precell mass analyzer for MC-ICPMS/MS using sector field technology. The new precell mass analyzer, comprising two Wien filters and a selection aperture, and a hexapole collision/reaction cell were integrated together in a single module and added to the commercially available Thermo Scientific Neptune XT MC-ICPMS to create a prototype MC-ICPMS/MS we named Vienna. Vienna was proven to retain the same performance of the base MC-ICPMS in terms of sensitivity, accuracy, and precision. Using the Vienna mass filter to eliminate Ar-based species, the abundance sensitivity achievable was equivalent to TIMS at mass 237.05, which was used to accurately determine the low 236 U/ 238 U isotope ratio of the uranium reference material IRMM184 (certified value, 1.2446 × 10 −7 ). The performance of Vienna was then tested for a variety of geoscience applications that were expected to benefit from MC-ICPMS/MS technique, including Ca, K, Si, and in situ Rb/Sr dating by laser ablation.

“…As a future option, the laboratory in Bristol, in collaboration with ThermoScientific, has recently developed a prototype of a MC-ICP-MS instrument that combines the use of CRC technology to overcome the spectral overlap and the simultaneous detection traditionally offered by this type of instrumentation, thus providing high precision and unbiased isotope ratio measurements for elements strongly affected by spectral interferences. 44 The possibilities of this instrumentation have already been demonstrated for Sr isotopic analysis using SF 6 as the CRC gas to overcome the spectral overlap of 87 Rb and 87 Sr in a mass-shift approach by monitoring the SrF + reaction product ions, a method similar to the one described in this work. However, this instrument is not yet commercially available, while the cost of this instrumentation also needs to be considered.…”

“…Thus, when it is not possible to digest part of the sample or for preselecting the samples prior to high-precision MC-ICP-MS analysis, LA-ICP-MS/MS offers a fast and minimally invasive way to determine the Sr isotopic composition of glass with high Rb/Sr elemental ratios and high REE concentrations, also allowing spatially resolved information to be obtained in a minimally invasive way.

Comparison of Minimally Invasive Inductively Coupled Plasma–Mass Spectrometry Approaches for Strontium Isotopic Analysis of Medieval Stained Glass with Elevated Rubidium and Rare-Earth Element Concentrations

Different approaches for the determination of the 87Sr/86Sr isotope ratio of high-Rb glass are compared in this work to assess the suitability of minimally invasive approaches for applications on medieval stained glass (from the ancient Abbey of Stavelot in Belgium). It was found that pneumatic nebulization multicollector inductively coupled plasma–mass spectrometry (PN-MC-ICP-MS) after acid digestion and chromatographic isolation of the target analyte out of the sample matrix can still be seen as the preferred method for the high-precision isotopic analysis of Sr in glass with high Rb and rare-earth element (REE) concentrations. Alternatively, the use of laser ablation (LA) for sample introduction is a powerful technique for the direct analysis of solid samples. However, both the high Rb/Sr ratios in the samples of interest and the presence of REEs at sufficiently high concentrations lead to a large bias in LA-MC-ICP-MS, which cannot be corrected for, even by operating the MC-ICP-MS instrument at higher mass resolution and/or using mathematical corrections. It was demonstrated that LA tandem-ICP-MS (LA-ICP-MS/MS) using CH3F/He as the reaction gas to overcome spectral overlap in a mass-shift approach (chemical resolution) provides a viable alternative when (quasi) nondestructive analysis is required. This approach relies on the monitoring of Sr+ (m/z = 86, 87, and 88) ions as the corresponding SrF+ reaction product ions (m/z = 105, 106, and 107), thus avoiding the occurrence of spectral interference. Self-evidently, the isotope ratio precision attainable using sequential quadrupole-based ICP-MS instrumentation (0.3% RSD) was found to be significantly worse than that of high-precision MC-ICP-MS (0.03% RSD) with simultaneous detection, although it was still fit for the purpose of current applications. In addition to Sr isotopic analysis, the REE patterns and their potential influence on the Sr isotopic composition were evaluated by LA-ICP-MS.

An automated parallel multi‐channel chromatographic system for isotopic analysis – Demonstration considering Sr

A fully automated, closed‐column chromatographic system with parallel multi‐channel has been developed. This system is established with seven reagent reservoirs, one multi‐channel syringe pump, eight 10‐port valves, forty sample tubes, 40 columns, and a fraction collection tray. Four samples can be purified simultaneously at a time, and 40 samples can be purified in one batch. Each sample can be purified by an independent channel, avoiding cross‐contamination. The sample tubes can be flipped upside down for automatic cleaning, which eliminates the residue of samples. Moreover, the fraction collection tray can collect up to 104 different target components. The key performance of the system has been investigated. The results show that the sample tubes are well‐cleaned, the bubble does not affect the chemical behavior of columns, the consistency of the parallel channels is excellent and the blank of the system is negligible. The system was demonstrated by the purification of Sr from reference materials (BCR‐2, JB‐2, JB‐3, and NIST SRM 987). The recoveries of Sr are better than 89.4% and the blank of the whole procedure is less than 200 pg. The Sr isotope values agree well with the reference values.
