Microplastics are everywhere you can’t see, from the mountains, to the ocean to your food. Identifying the degree of contamination requires analytical tools that can see subvisible particles as well as identify them.

In this webinar, Robin Sweeney, Product Manager at Unchained Labs, discusses recently published work highlighting the advantages of using advanced automated microscopy powered by the combination of Raman spectroscopy and laser-induced breakdown spectroscopy (LIBS) as a means to collect and identify microplastics in various samples.

Key Topics Include:

  • Gain data-driven insight on the advantages of Raman spectroscopy for microplastic identification
  • Overview of complete particle characterization from size, shape, and count to identification and source material
  • Advantages of an all-in-one automated system for particle characterization, especially microplastic particles
