1.4.3.2 Identification of Microplastics by Chemical Composition Pyrolysis‐GC/MS
ОглавлениеPyrolysis‐gas‐chromatography/mass spectrometry (Pyr‐GC/MS) can be used to determine the polymer types and additives. In this method, the samples are combusted, and the thermal degradation products of the polymers are used to detect MPs (Fries et al. 2013). The pyrolysis results provide characteristic pyrograms of MPs samples that can be identified by comparing with reference pyrograms of known polymer types. Particles must be inserted in pyrolysis tubes manually, and the technique can analyze only one particle per run; thus the method is unable for analyzing large amounts of samples (Dris et al. 2018; Klein et al. 2018).
