Minimizing Blanks and Lowering Detection Limits
In Episode 5, the panelists take a deep dive into one of the most critical aspects of PFAS analysis: minimizing background contamination and achieving lower detection limits. They discuss the pervasive issue of blanks—unintended contamination that can skew results—and the importance of rigorous quality control in both laboratory environments and analytical workflows.

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.
