title: Carbon disulfide measurement in marine waters using oxygen-doped electron capture detection with purge-trap preconcentration.
abstract: An oxygen-doped GC/ECD system has been found to be highly sensitive to carbon disulfide (CS(2)). The detector shows a linear response up to at least 13 pmol of CS(2) injected and has a detection limit of 30 fmol. By combining the oxygen-doped GC/ECD with a purge-trap system, CS(2) in seawater can be readily separated and determined. A comparison is provided between an oxygen-doped ECD and a nondoped ECD.
