PFSA Reference Spectra Paper

Can you investigate forever chemicals with ToF-SIMS? Why yes, yes you can! You’ll need high quality, annotated reference spectra, though. In this Surface Science Spectra article, we provide positive and negative polarity ToF-SIMS reference spectra for two representative perfluorosulfonic acids (PFSA) along with a general description of the fragmentation pattern of linear PFSA.
