Automatic Sample Preparation Device proposed as one of homoginized methods to collect natural microplastics in environmental waters

The occurrence of microplastics (MPs) and nanoplastics in the environment is global issue that requires the collaboration of multiple stakeholders to ensure the life cycle of plastics is properly monitored and managed. Most international efforts have focused so far on the standardization and validation of detection techniques, including Raman and FTIR spectroscopy and Py-GCMS. However, now that regulations for MPs are being developed and more environmental laboratories are starting their routine analysis, effective sample preparation is crucial for their success. Current approaches for eliminating organic content from samples or for separating inorganic materials rely on manual digestion and density separation, and the performance of these steps depends on the operator's proficiency. To obrtain more accurate data between laboratories, the homoginized method must be required. In this presentation, we will provide an overview of a universal sample preparation process suitable for the follow-up analysis by Raman, FTIR or Py-GCMS.
