Adapting GC-Based Standards for Sampling & Analysis of PFAS in Air

Learn how GC-based techniques widely used in VOC monitoring can be easily applied to PFAS analysis.

Exposure to per- and polyfluoroalkyl substances (PFAS) can occur through a number of pathways. One of the less understood, but equally important, routes is air. The movement of PFAS through air can happen relatively unimpeded when compared to water and soil, and deposition from the air is another way that they can become contaminated.

Sources of PFAS in the air can be industrial activity, disposal of PFAS containing materials or simply emissions from PFAS containing products. Monitoring of these different environments and matrices is commonly carried out using GC based techniques for other VOCs, so how does monitoring of PFAS differ? Join this webinar to hear about how techniques already broadly used for VOC monitoring can be successfully applied to PFAS measurements from air and materials.

By attending this webinar, you will learn:

• Which PFAS are GC amenable and which make most sense to monitor with other techniques

• How current VOC monitoring standards can be applied to PFAS monitoring in air

• What changes to those methods mean in terms of performance and new challenges they introduce

• What detection limits are possible in air and what is needed for different environments and matrices

Hannah Calder is Markes International’s Environmental Air Market Development Manager, specialising in the application of thermal desorption in environmental air monitoring. Hannah joined Markes International’s global team of technical experts in 2013 following her Masters degree in Chemistry obtained from Cardiff University. Hannah is involved with development of international analytical standards for ambient and indoor air monitoring through ASTM committee D22 and CEN committees TC264 and TC351. She has a comprehensive knowledge on the use of Thermal Desorption as an analytical tool for air analysis and is currently working on projects for monitoring ozone depleting substances, air toxics, ozone precursors, and PFAS.
