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)
A cryogenic purge and trap systems coupled to either a Hewlett-Packard 5890 Series II gas chromatograph and an Agilent 6890 gas chromatograph that were fitted with flame photometric detectors (DiTullio and Smith, 1995) were used to determine DMS and DMSP.
