Abstract

The evidence containing some kind of petroleum at the fire spot was analyzed by gas chromatographyto identify a fire's sources. To extract some petroleum from fire evidence, 10.0 mL of n-hexane was addedin this solution, and it was shaken for 30 minutes. To identify a kind of petroleum in fire evidence, the prepareddifferent from those of thinner and gasoline that have low boiling point, and shown diferent peak patern toheating and boiler oils. But it was similar to the chromatogram of diesel oil. After small amount of dieseloil was added to the sample, the area of characteristic peaks was increased more than those of raw sample.From the results, the kind of petroleum in the fire evidence was diesel oil.
