In the petroleum industry, sulfur compounds are one of the common GC analyzer systems and gas chromatography machines widely studied due to the incidence in quality control of petroleum products and petrochemicals during the refining of crude oil and in order to comply with environmental regulations.
Moreover, gas phase analysis consists in quantifying and/or identifying a mixture of compounds after being separated when establishing some physical weak interactions with a solid stationary phase. In particular, mercaptans, sulfides, hydrogen sulfide and carbonyl sulfide are the most common sulfur forms quantified in petroleum derivatives during exploration, production, transportation, storage, refining and processing of oil and gas.
