Equipment

Thermo Delta V Advantage (Green)

• Used for flash combustion analysis of organic matter from particulate matter on filters, plants, animals, and sediments. The instrument can easily be placed in concentration only mode using only the elemental analyzer if isotope analyses are not required. When interfaced with the Delta V Advantage via ConFloIV both N and C isotopes and concentrations can be obtained via continuous flow.
• Cost per analysis for N and C isotopes and concentrations: $8.00
• Cost per analysis for N and C concentrations only: $4.00

Picarro L2130i Cavity Ringdown Spectrometer (Green)

• Used for oxygen and deuterium isotopes in seawater and freshwater using a vaporizer and autosampler.
• Sample time is ~60 min/sample where each sample is comprised of 7 2.5ul injections. 
• Precision is  0.03 per mil for oxygen and 0.1 per mil for deuterium.
• Cost per analysis which includes both O and H/D isotopes: $10.00
• Throughput is ~20 unknowns/day.

Picarro G2101i Cavity Ringdown Spectrometer (Green)

• Used for carbon isotopes and concentrations in solids and liquids (TDIC). The CRDS uses a Picarro Liaison interface connected to an AutoMate carousel system. 
• Sample time is ~10 min/sample where each sample is comprised of 400 to 1000ug of pure CaCO₃ or 5ml of seawater with an average of 2mM concentration.  
• Precision is  0.05 per mil for carbon.
• Cost per analysis for either solids or liquids C isotopes and/or concentrations: $8.00.
• Throughput is ~40 unknowns/day.

Thermo Finnigan MAT 252 (Green)

• 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, and H₂O/CO₂ equilibrator
• Cost per analysis for O and C isotopes using the Kiel III: $10.00, 12 to 100ug sample, throughput 40 unknowns/day
• Cost per analysis for O and C isotopes using the 24 port manifold: $8.00, throughput 48 unknowns/day
• Cost per analysis for O and C isotopes using the H₂O/CO₂ equilibrator: $10.00, 1.5ml sample, throughput 20 unknowns/day
