Total sulfur in gasoline is determined by gas chromatography with a flame photometric detector. The analysis time is less than 5 min with a detection limit of 0.002% S (by weight) and a precision of + or - 10% for duplicate results by the same operator. The main source of error is the imprecision of injection of very small sample volumes (0.1 - 0.4 microliter). Gasoline samples with a sulfur concentration of up to 0.12% sulfur can be analyzed without dilution or sample preparation.
