Study on pyrolysis behavior of polymeric coated aluminium scrap using TGA and Py-GC/MS

Quantification of the composition of pyrolysis oils of complex plastic waste by gas chromatography coupled with mass spectrometer detector

“…Concerning quantitative composition of pyrolysis oils, during all these years the scientic community has normally used the "peak area percent" as the standard indicator for composition when using GC-MS. [14][15][16][17][18][19][20][21] However, the area percentage does not provide real information on the amount, because the signal intensity is not directly proportional to the concentration. Indeed, aspects such as the molecular weight of the species, the polarity, the selected chromatographic column, the volatility and the temperature inuence the signal obtained.…”
