Abstract
A method for the determination of C/sub 1/-C/sub 4/ alcohol content in gasoline by capillary column gas chromatography-ion trap detector system (GC-ITDS) is described. The method involves the direct injection of gasoline into the GC-ITDS, and subsequent detection of the alcohols using the multiple ion detection method. The detection method uses the mass-to-charge ratio peaks at 31 and 45 for the quantification of the alcohols. 1-Pentanol is used as an internal standard. The method was evaluated over the range of 0-20% for methanol and ethanol and 0-1% for 2-propanol, 1-propanol, 2-methyl-2-propanol, 1-methylpropanol, 2-methylpropanol, and 1-butanol. Detection limits for each of the alcohols are less than 0.1%.
