Episode 2: Maximizing EPA Method 1633 stability

EPA Method 1633 has quickly become a critical approach for PFAS analysis across complex environmental matrices, requiring consistent performance across demanding workflows and sample types.

In this session, explore practical strategies to maximize method stability on the SCIEX 7500+ system using real-world PFAS samples. Learn how instrument robustness, chromatography choices, and data processing decisions come together to support reliable, long-duration performance in high-throughput laboratories.

What you will learn

• How to optimize EPA Method 1633 workflows using real-world PFAS samples to improve stability and consistency
• The impact of calibration and regression models on extending calibration lifetime and reducing rework
• How chromatography, column health, and system setup influence method robustness and recovery
• Practical approaches to maintaining performance in high-throughput PFAS labs using SCIEX OS workflows and processing strategies

Ultrashort PFAS analysis at scale: From R&D to routine testing on the SCIEX 7500 system

Join SCIEX to see how PACE Analytical Services is generating defensible PFAS data in complex real-world samples beyond drinking water. In this virtual event, we’ll move past theory and show real chromatograms, matrix challenges, and practical decision points from PFAS work in the field.

What you will learn:

• Why ultra-short chain PFAS matter: Growing regulatory focus and why traditional methods struggle for these compounds
• Direct injection for lower cost and higher throughput: How direct aqueous injection simplifies workflows and reduces cost per sample
• Sensitivity and performance on the SCIEX 7500+ system: Achieving low-ppt detection limits while managing background and matrix effects
• Calibration, validation, and real-world samples: Real data from PACE data covering validation strategies, and performance in challenging matrices
• From R&D to routine testing: Practical lessons for implementing a robust, production-ready workflow

Speaker: Philip Bassignani, Pace Analytical Services
