ISO 19008 Nanoparticle Size Testing in Recycled Plastics
The ISO 19008 standard provides a robust framework for measuring nanoparticle size and distribution, particularly relevant to the recycled plastics industry. This service is pivotal for ensuring that materials meet stringent quality and environmental standards, thereby enhancing product performance while minimizing adverse effects on human health and the environment.
Recycled plastics are increasingly used in various applications due to their sustainability benefits and cost-effectiveness. However, the presence of nanoparticles can influence material properties such as mechanical strength, color stability, and biodegradability. Accurate nanoparticle size testing is essential for quality assurance and compliance with international regulations.
The ISO 19008 standard specifies a laser diffraction method using dynamic light scattering (DLS) to determine the size distribution of nanoparticles in recycled plastics. This method provides precise measurements, making it suitable for both research and production environments. The testing process involves several critical steps:
- Sample preparation: Ensuring that the sample is representative of the entire batch.
- Solution dispersion: Mixing the particles with a dispersant to achieve uniform suspension.
- Instrumentation setup: Calibrating the laser diffraction instrument according to manufacturer guidelines.
Once the samples are prepared and calibrated, the testing process proceeds as follows:
- The sample is introduced into the instrument's measurement chamber.
- Data acquisition begins immediately upon exposure of the particles to laser light.
- The resulting diffraction patterns are analyzed to determine particle size distribution.
Upon completion, a detailed report is generated, including statistical summaries and graphical representations of the data. This comprehensive approach ensures that all relevant parameters are captured accurately, providing valuable insights for quality control and process optimization.
| Sample Preparation | Data Acquisition | Analytical Output |
|---|---|---|
| - Ensure homogeneity of the sample - Use appropriate dispersants - Achieve fine particle dispersion |
- Calibration of laser diffraction instrument - Continuous data collection during measurement |
- Distribution curves - Mean diameter values - Polydispersity indices |
| Test Parameters | Methodology | Expected Outcomes |
|---|---|---|
| - Particle size range: 1–500 nm - Sample volume: 2 mL |
- Laser diffraction with DLS - Continuous measurement over time |
- Accurate particle size distribution - Reliable dispersion stability indices |
The precision and accuracy of these measurements are critical for ensuring that recycled plastics meet the required standards. This service plays a crucial role in enhancing product quality, reducing environmental impact, and fostering innovation within the industry.
