THE ANALYSIS OF SULFUR-COMPOUNDS BY SOLID ADSORBENT TENAX GR PRECONCENTRATION AND GAS-CHROMATOGRAPHY WITH FLAMELESS SULFUR CHEMILUMINESCENCE DETECTION

Gas chromatography using flameless sulfur chemiluminescence detection was applied to the analysis of sulfur compounds in air. A trap employi ng the solid adsorbent Tenax GR was used to enrich ambient levels of v olatile sulfur compounds. The sulfur gases were then thermally release d according to programmed temperature from the adsorbent trap and re-c ollected in a column cooled with liquid nitrogen. The sulfur compounds were revolatilized and directly transferred to the system of PLOT-col umn gas chromatograph/flameless sulfur chemiluminescence detector for analysis. The PTV injector has been used as a thermal desorption chamb er for analysis of sulfur compounds. The sulfur gaseous compounds know n to cause nuisance odors in the air from sewerage treatment works wer e determined.
