Event Overview
The detection and identification of thousands of PFAS compounds at very low concentrations can present a serious analytical challenge, often aggravated by the complexity of environmental matrixes in which these pollutants are found. Abundance of isomeric and previously unreported PFAS structures can make this task even more difficult. The combination of high-resolution mass spectrometry (MS) with high-resolution ion mobility spectrometry (IMS) allows reliable separation of isomeric PFAS compounds, while highly optimized methods of ionization in combination with collisional cross-section ion filtering provide high levels of sensitivity and analytical accuracy even in a complex matrix. Hardware performance combined with advanced data processing software enables identification of unknown compounds and streamlines a difficult analytical challenge into a manageable workflow.
Key Learning Objectives
- Understand how ion mobility enables high-sensitivity screening in a complex matrix.
- Learn how isomeric separation gives important information for identifying novel PFAS compounds.
- Learn how statistical and annotation tools in MetaboScape create a powerful non-targeted workflow.
Who Should Attend
- Environmental scientists, food scientists, polymer and industrial chemical scientists

New Method Explored for the Detection of CECs in Crops Irrigated with Contaminated Water
April 30th 2025This new study presents a validated QuEChERS–LC-MS/MS method for detecting eight persistent, mobile, and toxic substances in escarole, tomatoes, and tomato leaves irrigated with contaminated water.
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.
