Navigating PFAS Complexity: Addressing the Unique Chromatographic Challenges of Ultra‑Short‑Chain PFAS

PFAS, often referred to as “forever chemicals,” are a diverse class of anthropogenic compounds that have become a major public health concern. Their wide range of structures and frequent presence in laboratory materials create unique analytical challenges. These challenges are especially pronounced for ultra‑short‑chain PFAS, whose high polarity, limited retention on conventional reversed‑phase columns, and tendency to coelute with matrix components make them particularly difficult to separate and quantify. 

In this webinar, we will discuss key considerations for selecting an LC separation technique and choosing appropriate consumables—along with strategies to address the chromatographic complexities of ultra‑short‑chain PFAS—to help streamline PFAS analysis.

Emily Parry holds a Ph.D. in Environmental Chemistry from the University of California, Davis, where she studied how wastewater treatment transforms environmental contaminants. After completing her degree, she began her career conducting research at the Environmental Protection Agency (EPA) and the Public Health Institute. In 2018, she joined Agilent Technologies as an application scientist focused on small‑molecule analysis using LC‑QTOF and LC‑TQ, specializing in environmental applications. In 2026, she transitioned to Agilent’s LC columns group, where she supports customers and applications in small‑molecule separations. Over the years, she has developed deep expertise in analytical methods for measuring small molecules across diverse sample types.
