This webinar will examine the scientific principles underpinning fluorine sum parameter analysis and explore how CIC-based methods can be used to complement conventional PFAS investigations.

In this webinar, our speaker will explore:

• The historical development of organofluorine analysis and the emergence of fluorine mass balance concepts.
• Key fluorine sum parameters, including TF, TOF, EOF, and AOF.
• The principles and operation of combustion ion chromatography.
• Sample preparation approaches for water, soil, and other environmental matrices.
• Strengths and limitations of AOF, EOF, TOF, and TF methodologies.
• The role of fluorine mass balance in identifying unknown or unmeasured PFAS.
• Quality assurance and quality control considerations for CIC-based analysis.
• Factors influencing method selection, sensitivity, and data interpretation.
• Integration of fluorine sum parameters with targeted PFAS analytical results.

The presentation will draw on published research and practical examples to demonstrate how fluorine mass balance techniques can support PFAS investigations and improve understanding of the broader universe of fluorinated compounds present in environmental samples. Case studies will illustrate how TF, TOF, EOF, and AOF data can be interpreted alongside conventional PFAS analyses to support decision-making and reduce uncertainty.

This webinar will be particularly valuable for contaminated land consultants, environmental scientists, laboratory professionals, regulators, water industry practitioners, researchers, and risk assessment specialists involved in PFAS investigations and monitoring programs. A live Q&A will follow, and the session will be recorded.
