Addressing the Challenges of PFAS Analysis in a Variety of Matrices: From Air to Zipper Bags
Webinar Date/Time: Fri, Dec 2, 2022 11:00 AM EST
The extraction and analysis of PFAS present a range of challenges, and those challenges vary, depending on the sample matrix. Laboratory background is a concern in all cases. Join us to learn strategies for overcoming these difficulties.

Event Overview:
IPFAS is increasingly becoming a household term as more headlines reach more and more of the population. Although aqueous samples still make up the majority of PFAS tests, solid samples are generally increasing in numbers and aren’t limited to soils and sediments. Consumer products, tissues, and blood are now routinely tested for PFAS. PFAS in air also have multiple workflows ranging from stack emissions to ambient air. Each of these matrices has unique challenges associated with exhaustive extraction and quantitation of PFAS, which may require more than one instrument approach for success. The confidence in the quantitation of PFAS in these matrices heavily relies on isotope dilution techniques, which is integral to defensible data. Even with advanced instrumentation and a suite of isotopically labeled PFAS analogues, mitigation of laboratory background is a constant concern. All these factors are encountered on a daily basis and challenge the analytical laboratory. This study aims to survey the analytical approaches associated with the wide variety of matrices currently analyzed in the analytical laboratory.
Key Learning Objectives:
- How to address the challenges of extracting and measuring PFAS in a wide variety of matrices, including water, soils, air, and blood.
- Strategies for dealing with laboratory background levels of PFAS
- How to ensure confidence in the quantitation of PFAS
Who Should Attend:
Anyone interested in implementing a PFAS testing program or improving their existing testing activities.

Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
