Quantitation of Olefin Content in Plastic-Derived Pyrolysis Oils – QuadJet SD

This application note focuses on the quantitation of olefin content in plastic-derived pyrolysis oils using GC×GC-FID with the LECO QuadJet SD system and ChromaTOF Tile. Accurate identification and measurement of olefins are critical for evaluating pyrolysis oil quality and refining potential. The method combines comprehensive two-dimensional gas chromatography with flame ionization detection (GC×GC-FID), providing high resolution and quantitative accuracy for complex hydrocarbon mixtures. ChromaTOF Tile streamlines data interpretation by simplifying compound classification and comparison across samples. The study demonstrates how this approach allows users to differentiate olefin classes and quantify their concentration within diverse pyrolysis oil matrices. This solution offers chemical recyclers and researchers a powerful tool to assess material quality and guide process optimization in plastic-to-fuel or plastic-to-chemical workflows.
