Abstract

Arson is a serious crime that can cause extensive damage to both life and property. Identifying evidence to link suspects to the crime is, therefore, crucial. Detecting fuel residues provides valuable information for establishing connections between evidence and suspects. This study aimed to investigate the presence of gasoline residues on various types of fabrics using Fourier Transform Infrared Spectroscopy (FTIR). Specifically, 50 µl of gasoline was applied to six types of fabric samples: raw cotton, linen, nylon, polyester, rayon, and Italian silk. Gasoline samples from each fabric were collected at the following time intervals: immediately, 1 hour, 3 hours, and 6 hours, and analyzed using FTIR. The chromatograms identified the presence of gasoline components, including benzene, toluene, o-xylene, p-xylene, and ethyltoluene. The results showed that gasoline residues were detected in all samples even after 6 hours of exposure. Additionally, the amount of gasoline detected in the samples tended to decrease over time. This research has potential applications in detecting gasoline at crime scenes, thereby effectively aiding investigative process.
