Instrument: Mass Spectrometer

Instrument Short Name: Mass Spec
(http://vocab.nerc.ac.uk/collection/L05/current/LAB16/)
Instrument Description:

General term for instruments used to measure the mass-to-charge ratio of ions; generally used to find the composition of a sample by generating a mass spectrum representing the masses of sample components.

PI supplied instrument name: Delta V Plus
Dataset-specific description

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.
