Total sulfur analysis of various standard compounds, model fuel samples, and real gasoline samples was carried out using GC-FPD (GC coupled with a flame photometric detector), GC-PFPD (GC coupled with a pulsed flame photometric detector), and total sulfur analyzer (Antek 9000S). The nonlinear response of FPD and PFPD detectors for sulfur compounds and then quenching effect by the co-eluted hydrocarbons were examined. GC-FPD and GC-PFPD were unsuitable for quantitative analysis of the total sulfur concentration in complex hydrocarbon matrices if both the nonlinear response and the quenching effect, particularly for sulfur concentrations at low ppm level, were not considered. Ranges of errors from the application of GC-FPD and GC-PFPD for the total sulfur analysis were also analyzed. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
