Abstract:
The growing regulatory attention on PFAS, especially polymeric PFAS, demands effective analytical strategies for quantifying total organic fluorine (TOF) in complex materials. This presentation introduces a practical approach for determining TOF in polyolefin resins. Through selective solvent extraction from polyolefin resin, efficient defluorination of high molecular weight fluoropolymers, and sensitive GC detection of the derivatization product, this method achieves reliable quantification across a broad linear concentration range of 1-150 ppm. This GC-based approach provides a cost-effective solution for monitoring fluorine in a variety of applications to support both compliance and innovation in materials science.
