Abstract:
Cryogenic milling is a critical step in preparing water samples for microplastic (MP) analysis via pyrolysis-GC/MS. Using the IQ MILL-2070, filtered and oven-dried samples were efficiently pulverized under liquid nitrogen cooling, ensuring polymer integrity and homogeneity. This method minimizes thermal degradation and supports consistent, reproducible results. Cryo-milling enhances sample quality and lays the foundation for sensitive, trace-level MP detection, making it a valuable tool in environmental microplastic research.
