Forensic examination of petrol for adulteration by GC-MS

Abstract

The forensic examination of petrol for adulteration by gas chromatography-mass spectrometry (GC-MS) is a highly specialized analytical method that involves the use of advanced instrumentation to detect and identify various compounds that may be present in gasoline. The primary aim of this analytical technique is to determine the purity of the petrol, detect any adulterants, and provide evidence that can be used in legal proceedings. In this study, petrol samples collected from different states were analysed using GC-MS to identify the presence of adulterants. The chromatographic separation of the components in the petrol samples was achieved using a fused silica capillary column. The mass spectrometry analysis provided information on the identity and quantity of the compounds present in the samples. The results of the analysis were compared to the standard petrol sample, and showed that some of the petrol samples were adulterated with kerosene and diesel. The abstract demonstrates the utility of GC-MS in forensic analysis of petrol adulteration and its potential applications in forensic investigations.
