Analysis of Microplastic Polymer Using Pyrolysis GC/MS

Microplastics (MPs) encompass fine plastic particles with sizes ranging from several μm to about 5mm; their effect on ecosystems in the marine environment as well as other environmental compartments is of concern as the mass of microplastics in aquatic habitats will surpass that of the fish by 2050 (Pico and Barcelo, 2019). In addition to the negative impact from plastic ingestion, organisms can also bioaccumulate contaminants sorbed on MPs. There is a need for comprehensive analytical workflows to characterize microplastics, including major and trace components and sorbed contaminants, with the ultimate goal of understanding the fate and toxicity of MP in the environment. Pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) based methods are a tool of choice for qualitative and quantitative analysis of MP in complex environmental samples. High sensitive detection of the distinctive pyrolysis products of each polymer can be achieved. This poster demonstrates the performance of the Shimadzu GCMS-QP2020 NX with Frontier PY-3030D with AS-1020 Autoshot for characterizing a mixture of MPs.
