Total organofluorine, or organic fluorine, (TOF) analysis, refers to the measurement of fluorine that originates from any substance where fluorine is attached to a carbon backbone. It is gaining interest as a potentially faster and less expensive option for monitoring per- and polyfluoroalkyl substances (PFAS) impacts in soils, water and aqueous firefighting foam (AFFF). The test is distinct from routine PFAS analysis in that it reports a single result for a sample, representing the sum of fluorine arising from all organic fluorine substances measured, rather than individual results for different PFAS substances. Combustion ion chromatography (CIC) is a leading technology for a widely available, high-throughput, low-cost approach to TOF analysis. CIC has a long history of application to organohalide analysis for chloride, bromide and iodide species.

What You Will Learn

•    Understand a complimentary method and technique for discovering possible PFAS contamination
•    Learn how Absorbable Organic Fluorine (AOF) analysis by CIC is complimentary to targeted methods using triple quadrupole mass spectrometry
•    Explore how AOF fits different sample types

Chris Shevlin | Manager, Scientific & Educational Affairs | Thermo Fisher Scientific


Chris is the Manager, Scientific and Educational Affairs with the Ion Chromatography and Automated Sample Preparation group at Thermo Fisher Scientific. Chris started work in the lab in the 1990s, with a focus on HPLC. Since 2005, Chris has held a few different positions in sales, product management, and marketing, all within the chromatography and mass spectrometry industry. In 2015, he joined Thermo Fisher Scientific, first selling IC, GC, and LC systems before moving into a marketing role for ion chromatography and automated sample prep instruments. In 2021, Chris took on the new role as Manager, Scientific and Educational Affairs.

In his current role, he partners with many independent laboratories, regulatory agencies, and universities to help understand the challenges these labs face and their analytical needs in order to help them solve issues and streamline processes. Chris also helps with developing education content for ion chromatography and automated sample preparation instruments and applications.
