    Abstract: The programmed-temperature-vaporizing (PTV) injector has been developed as a thermal desorption chamber for simultaneous analysis of hydrogen sulfide (H/sub 2/S), methanethiol (CH/sub 3/SH), carbon disulfide (CS/sub 2/), dimethyl sulfide (DMS, CH/sub 3/SCH/sub 3/), and dimethyl disulfide (DMDS, CH/sub 3/SSCH/sub 3/). A trap employing the solid adsorbent Tenax-TA was used to enrich ambient levels of volatile sulfur compounds, then the sulfur gases were thermally released according to programmed temperature from the adsorbent trap and recollected in a column cooled with liquid nitrogen. The sulfur compounds were revolatilized and directly transferred to the system of capillary-column gas chromatography/flame-photometric detector for analysis . Analyses of environmental samples for the complete method of adsorption and temperature-programmed thermal desorption were successfully performed. The sulfur compounds known to cause nuisance odors in the air from various sulfur recovery and sewerage treatment works are compared.
