Abstract
The identification of “weathered” gasoline solely through gas chromatographic “fingerprints” of hydrocarbon portion is difficult. The polar components of three different “weathered” gasoline/water samples were analyzed by gas chromatography/mass spectrometry and compared to similar comeonents of the Same three gasolinos by this technique. This study shows that large portionsof gasoline additives are partitioned into the aqueous phase, and this information can be used as an aid in identifying a “weathered” gasoline samp1e.
