Used for high precision analysis of carbonate e.g., coral, forams, mollusks, gastropods, sediments, dolomite, enamel.

Typical precision of measurement: < 0.06 ‰ for O and < 0.03 ‰ for C

Time required for analysis: 30 minutes for both O and C

Cost per analysis: $10.00

Thermo Finnigan 24 Port Manifold

Used for high precision analysis of CO_{2} from any source.

Typical precision of measurement: < 0.05‰ for O and < 0.03 ‰ for C

Time required for analysis: 20 minutes for both O and C

Cost per analysis: $8.00

H_{2}O/CO_{2} Equilibrator

Used for high precision analysis of O in water via equilibration with CO_{2} and water. Water sample requires overnight equilibration with CO_{2} prior to analysis.

Typical precision of measurement: < 0.05 ‰ for O and C < 0.03 ‰ for C

Time required for analysis: 20 minutes for both O and C
