ClearStandard Test Method for Identification of Polymer Type and Quantity of Microplastic Particles and Fibers in Waters with High to Low Suspended Solids Using Pyrolysis-Gas Chromatography/Mass Spectrometry
This paper describes the development of an ASTM standard test method using pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) to identify and quantify specific polymer types in microplastic particles and fibers across a wide range of water types, from drinking water to marine water.
