Summary

Researchers used quantum cascade laser mid-infrared spectroscopy to test a methodology for classifying different consumer plastics by polymer type, evaluating its potential for microplastic identification in environmental samples. They demonstrated that QCL spectroscopy can distinguish between common polymer types, suggesting it as a promising analytical tool for polymer identification. The study presents preliminary results toward developing a new spectroscopic approach for environmental microplastic characterization.

We present preliminary results for a methodology to classify different consumer plastics using mid infrared spectroscopy with an external cavity quantum cascade laser (9.09 – 10.52 µm) for potential applications on microplastics identification in ecosystems.
