%X Complex techniques of sampling and determing main mal-ordors have been developed in this paper.Sampling on solid adsorbents followed by thermodesorption and GC/FPD and /or GC/MS was evaluated as a method for the quantitative analysis of CH3SH and (CH3)2S2 in air.Some apparatuses-Adsorbent Sampling Tube, Constant-flow sampling Pump, Thermodesorption Device and Gas Mixer for the preparation of calibration gas mixtures were developed and produced.The experimental results showed that the chinese-made GDX-105 was found suitable for adsorption and collection of CH3SH and (CH3)2S2 at the room temperature.The method affords recoveries between 60% and 100%.The limits of detection were 0.3 and 0.2 ng for CH3SH and (CH3)2S2.An accuracy of ±3% was obtained for the standard gases of CH3SH and (CH3)2S2 in the air or N2.
