Optimization of production process for microplastics reference materials
- Microplastics (MP) are defined as plastic particles mainly consisting of polymers in the size range of 1 to 1000 µm. They can be found in a wide range of environmental matrices but also in food products, indicating a potential risk on humans and environment. Plastic debris in the environment or food chain are extremely complex in terms of size, concentration, polymer type, levels of physiochemical degradation and undefined morphologies which makes their isolation and detection in complex matrices challenging. Analytical detection methods and techniques to identify and quantify microplastics in environmental and food matrices are numerous but validated and standardized methods are currently lacking. To close this research gap, reference materials (RMs) and representative sample preparation approaches are urgently needed. Homogeneity and stability are two crucial characteristics for the certification process of the reference materials. For this purpose, we aim to present ways to prepareMicroplastics (MP) are defined as plastic particles mainly consisting of polymers in the size range of 1 to 1000 µm.

To close this research gap, reference materials (RMs) and representative sample preparation approaches are urgently needed. Homogeneity and stability are two crucial characteristics for the certification process of the reference materials. For this purpose, we aim to present ways to prepare reference materials containing very low masses of close-to reality plastic particles with broad size distribution (10-100 µm) that are homogeneously distributed in tablet-to-tablet variation and stable over time. Our work is based on the ISO Guide 30:2015 and ISO Guide 35:2017 to fulfil the criteria set in future standards ISO/DIS 16094-2 and ISO/DIS 16094-3. The property of interest will be the mass detected by thermogravimetric analysis (TGA). Furthermore, informative values will be achieved by mass-based technique TED-GC/MS and spectroscopic microscopy techniques, such as µ-FTIR spectroscopy and µ-Raman.…
