Navigating PFAS Complexity: Addressing the Unique Chromatographic Challenges of Ultra‑Short‑Chain PFAS
27 May 2026 | 11 a.m. EST
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.

Column Chemistry Compass: Navigating the Agilent HPLC and UHPLC Column Landscape
28 July 2026 | 11 a.m. EST
Choosing the right HPLC column can be challenging given the wide range of stationary phases, particle technologies, and column dimensions available today. Whether you’re aiming to accelerate your separations, extend the performance of an older LC system, or unlock the full capability of a modern Agilent UHPLC platform, selecting the optimal column is key to achieving reliable, reproducible results.
In this webinar, we’ll explore how Agilent’s column technologies—from traditional fully porous ZORBAX materials to advanced superficially porous InfinityLab Poroshell particles—can be strategically matched to your instrument and your analytical goals. We’ll discuss how particle size and column dimensions influence efficiency and back pressure, helping you balance resolution, speed, or instrument compatibility.
Beyond standard C18 phases, we’ll highlight a range of Agilent bonded phase chemistries designed to enhance selectivity and help you make informed choices for your next HPLC or UHPLC separation.
Why Your Column Isn’t Always the Culprit: Smarter HPLC Troubleshooting
12 August 2026 | 11 a.m. EST
Unexpected changes to our chromatography often lead us to suspect the column first. But, in many cases, the true source of the problem is somewhere else in the system. In this webinar, we’ll explore some of the common chromatography issues we most often hear about as technical support specialists. Whether you’re dealing with shifts in retention time, pressure fluctuations, unexpected peaks, ghost peaks, missing peaks, or your peak shapes just don’t look right, we’ll walk through practical steps for diagnosing and resolving the problem. Having an understanding for where issues typically occur can help us to quickly identify the problem, implement the right corrective action, and prevent the problem from recurring in the future.
Comprehensive SEC Solutions: Performance and Application Insights Across Agilent’s SEC Columns
17 September 2026 | 11 a.m. EST
Size exclusion chromatography (SEC) is an essential technique for separating and characterizing biomolecules and polymers based on hydrodynamic size, enabling applications such as aggregate analysis of therapeutic proteins, assessment of viral vectors and nucleic acid therapeutics, and molecular‑weight profiling of synthetic polymers.
In this webinar, we will present a streamlined SEC workflow using Agilent LC platforms alongside Agilent’s full portfolio of SEC column solutions. The session will highlight performance characteristics, application fit, and best-practice method setup for multiple Agilent SEC columns—including our most advanced column technologies designed for high efficiency, minimal secondary interactions, and dependable robustness across complex sample types. Attendees will gain practical guidance on selecting the right column for their application, optimizing isocratic SEC conditions, and achieving reproducible, high-resolution separations in both R&D and QC environments.
Stocked for Success: Resources and Supplies to Minimize HPLC Downtime
8 October 2026 | 11 a.m. EST
If your goal is to maximize instrument uptime, then maintaining a well-stocked lab is your first step. Preventive maintenance is the key to minimizing instrument downtime. In this webinar, we will discuss which tools, supplies, and resources you should have on hand to maintain your instrument. Even with the best maintenance, sometimes instruments and methods need troubleshooting. This webinar will also discuss which resources and supplies can simplify your troubleshooting.
