Dual Inlet: Gas samples are analyzed via our dual inlet system in flame sealed glass tubes via tube breaker, or lecture bottles or similar that terminate with 1/4 fittings.
Gas Bench II: Samples are analyzed in 12-mL vials with septa caps. In some cases, use of our pre-evacuated vials may be possible. Contact the lab manager for details.
We use NIST, IAEA, and lab acquired carbonates digested with 100% H2PO4 for 13C and 18O normalization. QC carbonate samples, our CO2 monitoring gas and a CO2 flush fill tank provide monitoring of final calculated delta values.
