An evaluation of an analytical method for volatile sulphur compounds arose from the need to monitor compounds known to cause nuisance odours in atmospheres near sewage treatment works. A technique using thermal desorption from Tenax adsorbent, cold trapping and transfer on to a capillary GC column before chromatography which has been applied to qualitative analysis of a broad range of organic compounds by gas ciiraoratography-mass spectrometry was evaluated and subsequently modified to meet the demands of the analysis of a range of reactive volatile sulphur compounds by gas chromatography using a sulphur-selective flame photometric detector. Factors affecting recoveries from the adsorbent were identified and efficiency of transfer significantly improved.
