GC-MS Analysis on the Trace Residue of Gasoline Combustion

In this paper, GC-MS analysis of the gasoline combustion residue on composite wood floor, glazed tiles and concrete have been done under suitable conditions. Through experiments, homologues of benzene have been found to be the common characteristic components of gasoline combustion residues. The research proves that GC-MS analysis on the trace residue of gasoline combustion may be used to determine the existence of gasoline in a fire.
