ABSTRACT

Which technique is better for the characterization of microplastics in environmental samples: Raman or infrared? Micro-Raman spectroscopy makes it possible to analyze smaller particles than micro-infrared spectroscopy. The newly developed AIRsight Infrared/Raman microscope is an instrument that incorporates a Raman unit into an infrared microscope, enabling scientists to perform the analysis of microplastics on a single platform. In addition to the increased sensitivity Raman grants, this instrument provides two lines of evidence for identifying the nature of the polymers constituting the particles. In this presentation, we will share the performance of this dual technique for analyzing microplastics in environmental samples.
