After pyrolysis at 600 °C and enrichment of the degradation products on solid-phase absorbers, plastic species were quantified by GC-MS analysis detecting polymer-specific decomposition products [271]. Furthermore, unlike vibrational spectroscopy techniques such as Raman, it is not sensitive to variables such as colors. Raman method spectroscopy (<125 mm and >5 mass%) [266], micro-Raman spectroscopy (>100 µm), micro-FTIR spectroscopy (>100 µm) [267], m-Raman spectroscopy (>1 mm), m-FTIR spectroscopy (>10 mm) [268], macroscopic dimensioned near-infrared (NIR) in combination with chemometrics (>10 mm and 1 mass%) [266], and hyperspectral imaging technology (0.5-5 mm) can be used to identify plastics type, but these techniques are time-consuming, and they can be expensive and result in an uncertain extrapolation of MP quantity [269].
