Event Overview:

Per- and polyfluoroalkyl substances (PFAS) are exceptionally versatile chemicals and have seemingly endless applications. However, their persistent nature and prevalence in blood, food, and the environment, along with emerging concerns about their long-term toxicity, has led to efforts to detect and quantitate PFAS in serum and other biological samples. Analyzing PFAS is particularly challenging due to background contamination in laboratory supplies and systems. This webinar will cover sample preparation and LC-MS/MS analysis of an expanded panel of PFAS compounds in serum. We will present a microelution SPE method for 7 PFAS identified as significant by the National Academies of Sciences, Engineering, and Medicine for clinical research and biomonitoring in public health labs. Additionally, we will discuss strategies to reduce background contamination to improve limits of detection (LOD) and limits of quantification (LOQ), as well as LC separation techniques.

Key Learning Objectives:

• Describe LC-MS/MS and sample preparation options for PFAS in biological samples
• Identify challenges when extracting PFAS and helping overcome background contamination
• Explain sample preparation using microelution SPE

Who Should Attend:

• Environmental, clinical, and toxicology laboratory scientists
• Public health laboratory scientists doing biomonitoring
• Anyone interested in learning more about LC-MS/MS method development
• Anyone interested in PFAS analysis
