GC Analysis of Sulfur Compounds in Gasoline on SPB®-1 SULFUR

GC Analysis of Sulfur Compounds in Gasoline on SPB®-1 SULFUR


column SPB-1 SULFUR, 30 m x 0.32 mm I.D., 4.0 µm (24158)
oven 35 ºC, 5 ºC/min to 200 ºC
carrier gas helium, 20 cm/sec
sample Gasoline
injection 1 µL100:1 split
inj. temp. 275 °C
detector FID, 300 ºC; FPD, 300 ºC


Analysis Note Two issues must be overcome for the analysis of sulfur compounds in fuels. 1) Detection of these compounds in a hydrocarbon sample matrix, and 2) adsorption of these compounds by the column. Sulfur specific detectors, such as a flame photometric detector (FPD), can be used to overcome the first challenge. A low phase ratio column, such as the SPB-1 SULFUR, can be used to overcome the second challenge. This slide shows the analysis of a gasoline sample, in which the column effluent was split to two detectors. The top chromatogram shows the FID response, and the bottom chromatogram shows the FPD response.
