Thermo Finnigan MAT 252 (Green)

Thermo Finnigan Mat equipment
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: < 0.06 ‰ 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 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: $10.00
