Measurement of sulfur compounds is important to petroleum chemical analysts for several reasons, including a need to monitor odor problems and prevent catalyst poisoning.  Quantification of sulfur compounds is also important to environment analysts and to food, beverage and fragrance analysts for similar reasons.  Analyses of sulfur compounds can be complicated by the inability to resolve these compounds from the sample matrix, or from each other, and by adsorption in the chromatographic column.  A thick film, low phase ratio (low beta) capillary GC column gas been developed specifically for resolving sulfur compounds, from the light gases to the dimethylbenzothiophenes,  Analyses using an SPB-1 SULFUR column and sulfur-specific detection are shown here for sample matrices ranging from C1 through C24+ hydrocarbons.  Analyses of petroleum hydrocarbon gas and liquid streams, using flame ionization detection, are also shown.
