The Influence of Common Plastics on the Identification of Gasoline Studied by GC-MS

The influence of 5 kinds of plastics, PVC (Polyvinyl Chloride), PE (Polyethylene), PP (Polypropylene), PS (Polystyrene), ABS (Acrylonitrile Butadiene Styrene), and their mixture on the identification of gasoline was studied by GC-MS (Gas Chromatography-Mass spectrometry). The results showed that the influences are different among these plastics. However, all the plastics studied do not cause much change to the typical constitutions of gasoline combustion residue, resulting in the little interference on the gasoline identification according to the current criterion.
