Abstract Scope |
Vibrational Raman spectroscopy is a technique that can uniquely and quantitatively identify molecules and materials through their distinctive vibrational spectra. As an analytical tool, Raman spectroscopy has been used to tackle challenges related to biomedical imaging, energy conversion, and earth science. Despite Raman spectroscopy’s advantages of fast, reliable, and non-destructive detection, the technique suffers from low sensitivity. This limitation has kept Raman spectroscopy from being used to detect contaminants in atmospheric and aqueous environmental systems.
The research described in this presentation describes the adaptation of Cavity Enhanced Raman Spectroscopy (CERS) to detect environmental contaminants in aqueous and atmospheric systems. CERS leverages the advantages of Raman spectroscopy while improving detection limits by more than 3 orders of magnitude. While CERS has been demonstrated for model gas phase systems, it has never before been applied to environmental samples. We will use CERS to quantify aqueous phase contaminants including PFAS, and inorganic ions. |
