Residual accelerant from fire debris is the major evidence in the fire investigation. Because all evidences are almost damaged by fire, many isolation methods of analytical chemistry has been already used in extracting trace residue. In this paper, ultrasonic extraction is applied to isolate the residual accelerant and hexane as the solvent. The solution obtained from the residue is tested by GC-MS to analyze their total ion chromatogram (TIC). The chromatographic patterns observed for ignitable liquids are different from the patterns observed for without ignitable liquids. The composition of two samples and content of the fire residues have been analyzed. It’s very important for forensic chemist to distinguish the arson or natural fire.

A fire investigation is a difficult and challenging task. An investigator's basic task at a fire scene is two-fold: first, to ascertain the origin of the fire and, second, to closely investigate the site of origin and try to determine what triggered a fire to start at or near that spot. Usually, an investigation would begin by attempting to obtain a general view of the site and the fire damage; this may be achieved at ground level or from an elevated location. Following this, one may examine the materials available, the fuel load, and the condition of the debris at different locations. Surprisingly, the science of fire investigation is not stagnant, and each year, more information to assist investigators in determining the location and cause of a fire by diligent observation of the scene and laboratory study of fire debris is released. This chapter is split into two sections. The first section discusses the general procedures to be used during a fire investigation, and the second section discusses laboratory analysis of ignitable liquid residue analysis.
