Instrument: Gas Chromatograph
Instrument separating gases, volatile substances, or substances dissolved in a volatile solvent by transporting an inert gas through a column packed with a sorbent to a detector for assay. (from SeaDataNet, BODC)
For experiments 1-4, we used a Delta V Plus mass spectrometer interfaced with a Trace GC gas chromatograph through a GC-C III combustion furnace (980C), reduction furnace (650C), and liquid nitrogen cold trap as described in Hannides et al. (2009).
For experiments 5-6 we used a Delta V Plus mass spectrometer (Thermo Scientific) interfaced through a Conflo IV to a GC 1310 gas chromatograph coupled to a GC Isolink combustion-reduction furnace (1000C) and liquid nitrogen cold trap.
