Summary

This ASTM practice document describes standardized sample preparation procedures for water samples intended for microplastic analysis using Raman spectroscopy, infrared spectroscopy, or pyrolysis-GC/MS. The standard addresses the challenge of separating microplastics from background organic and inorganic material.

Significance and Use 5.1 Large volumes of water are required to be sieved for accurate quantification of microplastics. Water with high to medium content of suspended solids can lead to an excess of inorganic and organic background material which can inte
