Abstract:
The analysis of per- and polyfluoroalkyl substances (PFAS) in food and environmental matrices presents significant challenges for analysts. These compounds, widely used in manufacturing processes, have become pervasive, leading to potential sample contamination and elevated background signals in analytical instrumentation. In addition, material compatibility issues must be meticulously addressed to prevent analyte loss due to surface sorption.
Despite the inherent stability and chemical resistance of perfluorinated materials, hydrolytic and thermal degradation can occur within laboratory settings. Furthermore, regulatory agencies impose stringent low-level reporting limits, adding complexity to PFAS analysis. To tackle these obstacles effectively, a systematic approach to PFAS determination is essential. Analysts should optimize each step in the sample preparation and analysis workflow, from efficient sample extraction to robust data analysis.
In this informative webinar, we delve into strategies for optimizing the PFAS analysis workflow, sharing best practices and valuable tips-andtricks. The focus will be on current environmental methods and requirements (EPA methods 533, 537.1, 1633, ASTM D8421, and DoD/DOE QSM) and upcoming food testing methods (AOAC SMPR® 2023.003).
