Instruments and Fees

Thermo Finnigan MAT 252

Dual inlet instrument equipped with three peripherals for high precision analyses on carbonates, CO2, and water. This instrument is coupled to:
  • Kiel III carbonate device
  • 24 port manifold
  • H2O/CO2 equilibrator
Thermo Finnigan Kiel III Carbonate Device
Used for high precision analysis of carbonate e.g., coral, forams, mollusks, gastropods, sediments, dolomite, enamel.
Typical precision of measurement: < 0.05 ‰ for O and < 0.03 o/oo 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 CO2 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
 
H2O/CO2 Equilibrator
Used for high precision analysis of O in water via equilibration with CO2 and water. Water sample requires overnight equilibration with CO2 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
Cost per analysis: 12.00
