Abstract:
| Among the analytical techniques used for the analysis of microplastics, pyrolysis gas chromatography-mass spectrometry (py-GC-MS) presents a promising alternative for surveillance and identification of microplastics where throughput is critical. The study demonstrates that Py-GC-Orbitrap is a robust tool for the confirmation of the presence and identity of microplastics in different sample types. High selectivity and sensitivity were achieved in combination with a targeted screening approach using both Thermo Scientific™ Compound Discoverer software and Chromeleon™ software. The presented method allows for target microplastics analysis in different sample types, including complex food and environmental matrices. |
