Investigating the formation conditions of the first solids in the solar system using Large-Geometry SIMS

In this webinar Dr Yves Marrocchi, CRPG, Nancy, France presents recent petrographic observations and isotopic measurements of chondrules which shed new light on the timing of chondrule formation and how recycling processes during disk evolution led to the formation of chondrules.

Triple Oxygen Isotope Measurements by Multi-Collector Isotope by Multi-Collector large Geometry SIMS

Large-geometry SIMS equipped with a multicollector system (LG-SIMS) provide the best performance for geo- and cosmochemistry applications as they provide in situ analysis with both high spatial resolution and high precision. Recently, latest generations LG-SIMS were equipped with low noise 1012Ω resistor Faraday Cup preamplifier boards optimized for the measurement of low intensity signals. This talk describes an innovative path for triple oxygen isotope analyses, based on the measurement of the 17O minor isotope on a Faraday Cup detector equipped with a 1012Ω preamplifier board. This new analytical method allows nowadays to routinely measure oxygen isotopic ratios (18O/16O and 17O/16O) in various matrices with a precision (internal error and reproducibility) better than 0.5‰ (2σ), a spatial resolution smaller than 10 μm and in a few minutes per analysis. This work is the result of a collaboration between CAMECA and the CRPG Nancy lab in France.
