PFAS in Air: A Practical Toolkit for Real-world Applications
As focus expands beyond water and soil, laboratories face an urgent need to monitor volatile PFAS in air and consumer products, driving demand for robust, flexible analytical workflows capable of addressing an increasingly broad range of volatile and semi-volatile fluorinated compounds in air.
In this session, industry experts from Markes present a comprehensive, end-to-end integrated sampling and analysis toolkit for these emerging applications in air and materials.
Case studies will include industrial applications such as the characterization of products of incomplete destruction (PIDs) associated with PFAS remediation and thermal treatment processes, aligned with US EPA OTM-50 methodologies, stack emissions and landfill gas. In addition, ambient air monitoring for environmental impact assessment will be discussed with relation to developing CEN practices.
Indoor air applications will also be covered in the context of human health concerns, with reference to ASTM D8560 and ASTM D8591, demonstrating approaches for assessing PFAS emissions in occupied spaces. Additional examples will explore PFAS emissions from consumer materials within the home and food contact materials.
Emerging approaches for total fluorine screening and non-targeted PFAS analysis will also be introduced, addressing the need to identify unknown or novel fluorinated compounds beyond conventional targeted lists.
What You’ll Learn
- Have the opportunity to view a demonstration of compliant workflows spanning sample collection, introduction, pre-concentration, separation, detection, and data interpretation
- Learn how to assess PFAS off-gassing from consumer goods and food contact materials
- Discover strategies for characterizing Products of Incomplete Destruction (PIDs), stack emissions, and landfill gas emissions
- Explore approaches for total fluorine screening and identifying novel PFAS beyond the standard lists
Who should attend?
- Environmental consultants, testing laboratories, and regulators seeking practical, end-to-end workflows to support evolving PFAS standards, guidance, and regulatory requirements.
- Researchers and industry professionals working in PFAS remediation, product stewardship, materials development, or exposure assessment who need flexible tools for both targeted and non-targeted PFAS analysis.
