For studies of carbonate samples. Interfaced with the Delta Plus XL for continuous flow analysis of O and C isotopes.

Typical precision of measurement: < 0.2 ‰ for both O and C

Time required for analysis: ~15 minutes for both O and C

Cost per analysis: $8.00

Costech Elemental Analyzer

For flash combusion analysis of organic matter from plants, animals, and organic matter contained in sediments. Interfaced with the Delta Plus XL for continuous flow analysis of primari\ly N and C isotopes (S can be analyzed, but requires changes in instrument configuration).

Typical precision of measurement:
<0.2 ‰ for N and C isotopes
<1% for both N and C concentrations

Time required for analysis: ~10 minutes for both N and C

Cost per analysis: $8.00

Thermo Finnigan High Temperature Conversion Elemental Analyzer (TC/EA)

For high temperature conversion (pyrolysis) of selected minerals, organic matter, and water. Interfaced with the Delta Plus XL for continuous flow analysis of H and O isotopes.
