Determination of adsorbable organically bound fluorine (AOF) and adsorbable organically bound halogens as sum parameters in aqueous environmental samples using combustion ion chromatography (CIC).

Because of their toxicity and biomagnification potential individual perfluoroalkyl and polyfluoroalkyl substances (PFAS) are regularly examined in food and environmental matrices by LC-MS/MS. The combustion ion chromatography (CIC) can be used to determine adsorbable organic fluorine (AOF) in aqueous samples. This report describes the optimization and validation of an automated, robust, cost-efficient and rapid CIC method for the determination of AOF.
