Specific features of the determination of hydrogen sulfide in the presence of hydrogen were studied by gas chromatography with the use of a thermal conductivity detector and argon as the carrier gas. A chromatographic column with HayeSep A modified with 10 wt % H3PO4 was proposed for the simultaneous determination of both components. It was demonstrated that the elution curve of hydrogen sulfide in an argon atmosphere has a non-Gaussian shape because of the interaction of hydrogen sulfide with the tungsten filament of the sensing element of the catarometer. To eliminate this interaction, it was recommended that a gold-plated tungsten filament be used in the detector.
