The purpose of this research is to identify the major components in low vs high octane gasoline samples. Samples of 87 and 91 octane gasoline will be obtained from local gasoline stations and will analyzed using GC/MS. Identification will be made using the on-line NIST mass spectral library as well as analyzing known standards. Low and high octane gasoline will be compared from the same gas station as well as from different manufactures. It is expected that more aromatics will be found in the high octane gasolines.
