PY-GCMS 微塑料热裂解分析

Pyrolysis–gas chromatography–mass spectrometry (Py-GC-MS) is a method of chemical analysis where a sample is introduced to an anaerobically heated environment and broken down into smaller stable fragments or components through controlled thermal degradation (pyrolysis). The use of Py-GC-MS allows researchers to perform qualitative and quantitative analysis of components in environmental specimens. By eliminating the need for extraction and dilution sample preparation, Py-GC-MS can characterize a wide variety of polymers and composite materials that cannot be analyzed using traditional GC-MS methods. The Py-GC-MS technique is suitable for a variety of environmental applications, including the identification and characterization of micro- and nano-plastic contamination.
