Analytical Methods (2016), V8, pp1721-1727, doi: 10.1039/c5ay00613a

Goal: A new method has been developed for the accurate, precise and more rapid determination of boron isotopes (?11B) by MC-ICP-MS applicable to seawater and pore water samples. Obvious matrix effects have been observed when applying pure standard solutions to bracket the untreated pore water samples and matrix-containing standards. The matrix effects were eliminated by applying matrix-matched standards to measure the matrix-matched ones.

Geochemistry, Geophysics, Geosystems (2014), V15, pp121-139, doi: 10.1002/2013GC004962

Goal: The “laser ablation split stream” (LASS) technique is a powerful tool for mineral-scale isotope analyses and in particular, for concurrent determination of age and Hf isotope composition of zircon. Because LASS utilizes two independent mass spectrometers, a large range of masses can be measured during a single ablation, and thus, the same sample volume can be analyzed for multiple geochemical systems. This paper describes a simple analytical setup using a laser ablation system coupled to a single-collector (for U-Pb age determination) and a multicollector (for Hf isotope analyses) inductively coupled plasma mass spectrometer (MC-ICPMS).

Journal of Analytical Atomic Spectrometry (2015), V30, pp994-1000, doi: 10.1039/c4ja00449c

Goal: This study presents a combined methodology of simultaneously measuring Rb–Sr/Sm–Nd or Sm–Nd/Lu–Hf isotopes in natural minerals by a means of two multiple collector inductively coupled plasma mass spectrometers (MC-ICP-MSs) connected to a 193 nm excimer laser ablation system. The ablated materials carried out of the HelEx cell by helium gas are split into two gas streams with different proportions into the Neptune for Sr (or Nd) analyses and Neptune Plus for Nd (or Hf) analyses.

13C18O16O in air

Goal: The atmospheric budget of CO2 is constrained by its concentration, δ13C and δ18O. However, these are insufficient to resolve source and sink processes, which vary complexly in flux and/or isotope signature. There are twelve stable isotopologues of CO2, each of which has unique thermodynamic and kinetic properties and could offer unique constraints on the budget.

Improved detection of honey adulteration by measuring differences between 13C/12C stable carbon isotope ratios of protein and sugar compounds with a combination of elemental analyzer - isotope ratio mass spectrometry and liquid chromatography - isotope ratio mass spectrometry ( 13C-EA/LC-IRMS)

Goal: The detection of honey adulteration with invert sugar syrups from various C3 and C4 plant sources was realized by coupling an isotope ratio mass spectrometer both to an elemental analyzer and to a liquid chromatograph (EA/LC-IRMS). For 451 authentic honeys measured, the individual δ13C values of bulk honey, its protein fraction, fructose, glucose, and di- and trisaccharides ranged from –22.5 to –28.2 permil and did not show differences (Δδ13C) of more than +/-0.9 permil (average), with a maximum standard deviation of 0.7 permil. The Δδ13C (fructose – glucose) value was significantly lower (0+/- 0.3 permil). The newly developed EA/LC-IRMS method and the purity criteria defined represent a significant improvement compared to existing methods.

Goal: Carbonate clumped isotopes offer a potentially transformational tool to interpret Earth’s history, but the proxy is still limited by poor interlaboratory reproducibility. Here, we focus on the uncertainties
that result from the analysis of only a few replicate measurements to understand the extent to which unconstrained errors affect calibration relationships and paleoclimate reconstructions.
