Web Seminar: Monitoring PFAS and Other Organically Bound Halogens in Water and Wastewater

How to determine AOX and AOF by Combustion Elemental Analysis and Combustion Ion Chromatography

As the presence of organically bound halogens (AOX) and organically bound fluorine (AOF) in the environment is coming under scrutiny in many countries, there is a need for rapid screening of these parameters in environmental samples. 

In a joint web seminar by Analytik Jena and Metrohm, Christian Koch (Analytik Jena) and Theresa Steurer (Metrohm) present Combustion Elemental Analysis and Combustion Ion Chromatography (CIC) as a viable solution to determine the sum parameters AOX and AOF. 
In contrast to other techniques CIC can determine the individual sum parameters of the individual halogens, e.g., AOF, which is a screening parameter for per-and polyfluorinated alkyl substances (PFAS). Thus, CIC can provide a fast and accurate picture of the overall contamination levels before performing targeted analysis to identify individual PFAS.

As sample preparation is a crucial step in both techniques, this web seminar puts a special focus on procedures making sure that only the organic halogen compounds are measured and any interfering compounds are removed prior to analysis (see ISO 9562; EPA 1650C, and notably recently published DIN 38409-59).
