Total Fluorine and Extractable Organofluorine Analysis
topic
Total fluorine analysis by combustion ion chromatography provides a mass balance of all fluorine in a textile specimen, while extractable organofluorine analysis uses liquid extraction followed by activated carbon enrichment and combustion IC quantification of the organic fluorine fraction; the difference between total and inorganic fluorine indicates total organic fluorine burden beyond individual targeted PFAS analytes.
Role
Addresses the limitation of targeted PFAS methods by capturing the total organofluorine load including unknown and emerging PFAS precursor compounds not covered by targeted analytical panels, providing a conservative screening tool for fluorine-free claim verification and total PFAS burden assessment in textiles.
