Near-Infrared (NIR) spectroscopy combined with chemometrics for microplastic quantification

The characterization of microplastics (MPs) in environmental matrices is frequently hampered by the spectral complexity of heterogeneous mixtures and the presence of interferents. This study has validated a new analytical framework using portable Near-Infrared (NIR) spectroscopy combined with chemometric modelling to move beyond qualitative detection toward field quantification: Cruz Muñoz, E., Marchesi, C., Rigo, M., Ali, S., Depero, L., de Lucia, G., Camedda, A., Prati, S., Ballabio, D., Sciutto, G., Federici, S.
