Stable Isotope Biogeochemistry Laboratory (SIBLab)

The Stable Isotope Biogeochemistry Laboratory (SIBLab) facility is located in Prof. Grottoli’s lab in the School of Earth Sciences. Analytical equipment includes a Delta IV stable isotope ratio mass spectrometer (SIRMS) coupled to an automated carbonate Kiel III device, a Costech elemental analyzer (EA) coupled to the SIRMS via a Conflo III interface, and a gas multi-port (MP) inlet system coupled to the SIRMS.  If interested in submitting samples for analyses, please complete the SIBLab Sample Submission Form 2015 and contact Professor Grottoli (grottoli.1@osu.edu).

SIB Lab analyses charges for 2015

Inorganic carbonates (vial Kiel-SIRMS) for δ18O and δ13C analyses – $12.50/sample

Organic matter submitted as a dry powder (via EA-SIRMS) for δ15N and δ13C analyses – $12/sample

Organic matter loaded on filters (i.e., POM) (via EA-SIRMS) for δ15N and δ13C analyses – $26/sample

Gas ampoules (vial Multiport-SIRMS) for stable isotope analyses (which isotopes will depend on the sample) – $12.50/sample

Quoted prices are subject to change. Minimum charge of $300 for 1 – 15 powdered organic, carbonate, or gas samples.  Duplicates and standards are included. The per sample cost assumes that clients load their own samples and standards. Please allow for a 5% per year increase when projecting costs.  For OSU SES members, deduct $1/sample for organic samples and $0.50/sample for all others sample types.
