Analysis of Sulfur Compounds Using On-line and Off-line TD–GC

Sulfur compounds are associated with unpleasant, pungent odors that are noticeable even at low concentrations. These compounds are difficult to analyze, as they are thermally labile (sensitive to high temperatures), particularly when in contact with metals. Moreover, several of the compounds of interest, such as hydrogen sulfide and methanethiol, are very volatile.
