ACCESS GUIDE TO THE Wisc-SIMS LABORATORY
As a NSF multi-user Facility, we provide support to external users who come to the laboratory and use the IMS-1280.
Currently, the following stable isotope analyses are well-established and routinely available to external users.
Oxygen isotope analyses (δ18O) with ~10µm spots:
Zircon, quartz, olivine, pyroxene, calcite, aragonite, dolomite, plagioclase, K-feldspar, spinel: precision typically <0.2‰ (1SD)
Carbon isotope (δ13C) with ~8µm spots:
Diamond, graphite: precision typically <0.2‰ (1SD)
Calcite, aragonite, dolomite: precision typically <0.3‰ (1SD)
Sulfur isotope (δ34S) with ~10µm spots:
Pyrite and pyrrhotite: precision typically <0.2‰ (1SD)
Analyses take 5-10 minutes per spot.
Other applications with more difficult samples, or with Li, Mg, and Si isotopes are also available. Please contact us for more detailed information.
APPLICATIONS FOR INSTRUMENT TIME should be sent to Wisc-SIMS with a brief description of the project and samples. The Wisc-SIMS Oversight Board allocates instrument time according to the scientific merits and feasibility of the project. Applications should be made by grant PIs.
FEE SCHEDULE:
Since Wisc-SIMS receives a subsidy from NSF/EAR Instrumentation and Facilities Program, external NSF-funded investigators receive priority in allocation of the instrument time and are eligible to perform analyses at a subsidized rate. The current subsidized rate is $1,440/day (12 hours), applied to US federally-funded research. The unsubsidized rate is $3,600/day (12 hours).
PUBLICATION AND ACKNOWLEDGEMENT:
We request that any data produced from Wisc-SIMS lab explicitly recognize NSF support in the acknowledgements of the journal articles with the following sentence: "Wisc-SIMS is partly supported by NSF (EAR03-19230, EAR07-44079)."
