How to identify colorless microplastic directly in the beach sand in a few minutes?
Summary
Researchers developed a high-throughput near-infrared hyperspectral imaging technique to automatically detect and identify colorless microplastics directly in beach sand within a few minutes. The chemometric classification model can identify multiple plastic polymer types without requiring chemical pre-treatment.
Development of a high throughput screening technique based on line-scan near-infrared hyperspectral imaging (HSI-NIR) and chemometrics to automatically detect and identify microplastics. Chemometrics were performed with soft independent modelling of class analogy (SIMCA). The supervised classification model was built for microplastic automated identification.
