Equipment

Finnigan Delta V (Mitchell)

Continuous flow instrument for intramolecular N isotopomers and O isotopes of nitrous oxide, as well as N and O isotopes of nitrate and nitrite. Coupled with a GC-Pal autosampler, purge-and-trap system, and GC for analysis of dissolved N2O in seawater.

Finnigan Delta XP (Mitchell)

Continuous flow instrument for N and O isotopes in nitrate and nitrite. Coupled with a GC-Pal autosampler and gas bench for fully automated analysis of liquid samples.

Thermo Delta V Advantage (Green)

lab equipment - Thermo Delta V Advantage IRMS

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.

Thermo Finnigan Deltaplus XL (Mitchell)

Dual inlet and continuous flow capabilities, interfaced (ConFlo III open split interface) with:

    Gasbench
    Costech EA
    TC/EA

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
    H₂O/CO₂equilibrator

Thermo Finnigan MAT 252 (Mitchell)

For the oxygen isotope analysis of silicate and oxide minerals. Attached is a BrF5 infrared laser line.

ThermoFisher 253 Plus (Mitchell)

For the analysis of oxygen 17 in silicates, carbonate, and oxide minerals. Attached in a BrF5 laser-line with an infrared laser.
