This webinar fill focus on PFAS extraction and analysis from various food samples, include eggs, fish, butter and Food contact material. We will present a two-step extraction procedure of 23 PFAS analytes from butter, making use of QuEChERS followed by Solid Phase Extraction and analyzed by LCMS/MS. The high resolution and unique mixed-mode selectivity of a Luna? Omega 1.6 μm PS C18 LC column results in excellent chromatography in a very short 4-minute run. In addition, further analysis of milk, eggs, and fish tissue were also validated using the method. Results from various butter sources indicate that different packaging results in differences in the PFAS compounds present.

Abstract: Per- and polyfluoroalkyl substances (PFAS) have excellent stain repellent properties and are thus widely used in packaging materials, firefighting foams and many other applications. As PFAS have been found in virtually every environmental matrix studied including drinking water, monitoring is critical to support consumer safety. Here, a quantitative method for a suite of PFASs was developed for analyzing water samples. Data generated for this test are compared using the SCIEX 6500+ and 7500 systems. This sensitivity of the SCIEX 7500 system provided signal-to-noise gains of ~5.5x on average across the 54 compounds analyzed versus the SCIEX 6500+ system.
