✦ Synopsis

Addition of a reactant gas to a low pressure microwave-induced plasma creates a reaction interface in which complex molecules are converted into small polyatomic neutral species. For a given reactant gas the array of these small molecules reflects the elemental composition of the original analyte. In this study HCl has been found highly effective as a reactant gas for selective detection of sulfur-containing compounds using capillary gas chromatography/chemical reaction interface mass spectrometry. Detection limits as low as 30 pg of a sulfur-containing compound and a dynamic range of two orders of magnitude were achieved. (
