Effective sample preparation is crucial for accurate PFAS analysis, especially as PFAS testing becomes more widespread and regulated, particularly in complex matrices like food, non-potable water samples, soils, and tissue. This webinar will focus on the importance of method robustness and recent advances and the importance of solid-phase extraction to ensure acceptable recoveries and reproducibility for PFAS analysis.

This webinar will highlight three applications for PFAS determination from food and environmental matrices including:

  • Analysis of 28 EU regulated and recommended PFAS from vegetable, fruit, and baby food samples
  • An automated approach using the Andrew+ robot for analysis of PFAS from milk matrices
  • Analysis of PFAS in accordance with EPA 1633 for aqueous, soil, and tissue samples

Additionally, we will demonstrate the use of new Oasis WAX/GCB and GCB/WAX for PFAS Analysis cartridges for EPA Method 1633 and food applications and the cartridges’ benefits. Join us to learn more about ways to enhance your PFAS analysis.

Key Learnings:

  • Understand importance of robust sample preparation in PFAS analysis
  • Examine specific food and environmental applications and methods for PFAS determinate from a wide variety of matrices
  • Learn about recent advances in sample preparation products and automation to enhance efficiency, cleanliness, and accuracy for PFAS workflows

Stuart Adams

Consulting Scientist, Waters Corporation


Stuart started his career by attending the University of Glasgow studying for an honours degree in Food and Environmental Chemistry where his passion for solving analytical challenges started. He furthered his education with a doctorate from the University of Leeds in analytical chemist. Subsequently he spent 17 years working at Fera on a variety of projects looking at the detection of chemicals in challenging food and environmental samples using a variety of detection techniques. Whilst at Fera he has represented the UK at several European Union Reference Laboratory meetings for pesticide analysis and is a recognised international expert in his field. Stuart joined Waters Corporation in 2018 and currently works as a Consulting Scientist where he still loves to work on solving the analytical challenges that matter.

Daniel Ng received his PhD from the University of Manchester in mass spectrometry proteomics. He worked for 5 years at the Waters mass spectrometry headquarters in Wilmslow, UK, as a service support development engineer specializing in mass spectrometry instrumentation. In 2019, he took up a new role as a principal scientist at the International Food and Water Research Centre (Waters) in Singapore focusing on using advanced instrumentation to answer analytical challenges in the food and water industry. Since 2023, Daniel has lead the Food, Environmental and Material Science Analytical Professional Service team in the Asia-Pacific Region, developing analytical solutions to meet key challenges that customers face.


Kari Organtini, PhD

Principal Scientist, Waters Corporation


Kari Organtini is a principal scientist at Waters Corporation and has been with the company for eight years. She received her PhD from Penn State University in 2015 studying the occurrence of dioxins and furans in fire debris and their implications to first responder health. At Waters, Kari is part of the PFAS Program in the Testing and Lab Services Group. Kari has developed applications using both LC and GC techniques for a variety of applications ranging from pesticides to persistent organic pollutants during her career. She is currently the scientific lead for developing PFAS applications at Waters.


Marcus Devakishen

Intern Researcher, Student, Waters Corporation, Nanyan Technological University


Marcus Devakishen is a final year undergraduate student from Nanyang Technological University (Singapore), and will be graduating with a Bachelors in Chemistry this year. His project with Waters is to develop next generation automation workflow solutions in the area of PFAS analysis, and has contributed to Andrew+ automation workflows of PFAS sample extraction in different matrices such as food and fire-fighting foam, and explored higher throughput of PFAS extraction analysis through the use of 96-well plates and multi-channel pipettes.
