ABSTRACT
A system has been developed for the identification of trace amounts of petroleum products from the debris of fires using a Bentone 34 + Di-isodecylphthalate (DIDP) column. Samples were obtained in the vapour state by the following three methods:
| 1) | Headspace sampling at room temperature. | ||||
| 2) | Headspace sampling after heating in an oven. | ||||
| 3) | Sampling from the condenser during distillation. | ||||
Gasoline and naphtha can be readily differentiated from other accelerants and contaminants. A large percentage of arson cases require no further examination than the oven heating method followed by G.C. analysis.
