Until now, the analysis of targeted polyfluorinated substances (PFAS) has seemed sufficient to determine the environmental impact of this large group of manmade, highly fluorinated substances. With thousands of PFAS compounds now identified, the attention has shifted to non-targeted analysis as it provides a better understanding of the total impact these PFAS compounds have on the environment. Consensus is forming among scientists that the analysis of total organic fluorine (TOF) provides a better overall picture of PFAS impact and, as a result, an improved approach to this analysis is needed. Non-targeted techniques are of particular interest to the regulatory communities in Europe and the United States. This session will present how the new Profiler-F Total Fluorine Analyzer enables the determination of TOF in wastewater and industrial process water samples with simultaneous total and free fluorine quantification.
