Determination of odorous sulfur compounds in air by Tenax GR preconcentration and capillary gas chromatography in combination with flameless sulfur chemiluminescence detection

A liner of PTV injector packed with the solid adsorbent Tenax GR was used to enrich ambient levels of volatile sulfur compounds, then the sulfur gases were thermally released according to programmed temperature from Tenax GR trap and re‐collected in a column cooled with liquid nitrogen. The sulfur compounds were revolatilized and directly transferred to the system of capillary‐column gas chromatography/flameless sulfur chemiluminescence detector for analysis. The PTV injector has been used as a thermal desorption chamber for determination of sulfur compounds. The sulfur gaseous compounds known to cause nuisance odors in the air from sewerage treatment tanks of a chemical petroleum company and hoggery are determined.
