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)
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:
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
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.
