WEBINAR: Capturing the PFAS Footprint and Potential Hotspots: LC-MS/MS vs. a New Total Organic Fluorine Method

Unraveling PFAS Complexity

The story of PFAS is a fast evolving one and ensuring that you have all the information and equipment that you need to successfully perform PFAS testing is vital. In this series of webinars we discuss regulatory requirements, screening techniques and the analysis of targeted and non-targeted PFAS for the modern analytical testing laboratory.

LC-MS/MS is the gold standard for measuring PFAS in the environment with the ability to capture low- and even sub-parts-per trillion levels. However, standards are only available for a limited number of PFAS, such that quantitative methods only capture a small part of the PFAS footprint. This presentation will detail the development of two new Total Organic Fluorine methods that use combustion-ion chromatography to more comprehensively capture PFAS, capturing known and unknown organic fluorine. Professor Richardson will also show results from a statewide mapping of South Carolina surface waters using one of these new Total Organic Fluorine methods and compare to what we can measure using LC-MS/MS. Learning points: 

• How total organic fluorine methods work
• How up to 99% more PFAS in environmental samples can be captured compared to target LC-MS/MS methods
• How Total Organic Fluorine can be used to find PFAS hotspots
