Abstract

Fire accelerants are commonly used in arson. As after combustion their chromatogram changes, the goal of this project is to provide reliable data to detect their permanence in the burned samples. Initially, burned, and unburned samples of different accelerants in contact with sbustrates are generated and analyzed in three laboratories using a Gas chromatography - mass Spectrometer. From the received results it is observed that the compounds found by them are too variable and cannot be compared. Then, an individual analysis is done and some trace patterns from the accelerants are found remaining in the fire debris. The main permanence is from the aromatic components and the heavier hydrocarbons, while the lighter ones are less or not detected in the chromatograms.
