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.
Gas Bench II
Samples are analyzed in 12-mL vials with septa caps. If desired, our staff can pipet water samples to vials for a minimal charge per sample. In some cases, use of our pre-evacuated vials may be possible. Contact the lab manager for details.
TC/EA
We use a GC PAL autosampler and modified reactor for liquid injections on the TC/EA. Samples should be in 2 mL screw top vials (12×32 mm) with 8mm diameter septa caps. If desired, WSU laboratory staff can pipet samples into vials for a minimal charge. In the event of small samples, vial inserts can be used.
