PlastiTrax® Particles
| Fragments |
All microplastic fragments are produced in-house using a polymer-specific cryogenic milling process, ensuring controlled and reproducible particle generation. Following milling, a custom-developed wet sieving procedure is applied to separate the particles into defined size fractions.
This approach minimizes the formation of particle agglomerates and ensures a reliable and consistent size distribution for high-quality microplastic analysis.
| Density|
All microplastic fragments are produced from prestine polymer granulates, ensuring well-defined and reproducible material properties. In particular, the polymer density plays a critical role in microplastic analysis, especially for density-based separation processes. By using pure source materials, the intrinsic densities of the polymers are preserved, enabling reliable evaluation of separation efficiency and realistic spectral signatures.
Optical Charakterization
The resulting fragments exhibit irregular and diverse shapes, similar to those found in environmental samples. Particle morphology varies depending on the polymer type, ranging from fiber-like structures to more rounded fragments. This variability reflects real-world conditions and enables environmentally relevant and realistic measurements in microplastic analysis.
Each particle fraction is morphologically verified using microscopy and spectroscopic imaging techniques.
Polycarbonat (PC) fragments in size range 100-200 µm
Polymethyl Methacrylate (PMMA) fragments in size range 50-100 µm.
Polyvinylchloride (PVC) fragments in size range 25-50 µm.
Polystyrene (PS) fragments in size range 20-25 µm.
