Odour emissions are often associated with, but not limited to sulphur compounds due to their unpleasant, pungent odours,
which are noticeable even at low concentrations.
These compounds are difficult to analyse as they are thermally labile (sensitive
to high temperatures), particularly when in contact with metals.
Moreover, several of the compounds of interest are very
volatile, such as hydrogen sulfide and methanethiol.
Markes’ TD technology has been shown to be compatible with on- and off-line monitoring of trace sulfur compounds in both standards and real-world samples.
