Overcoming the Challenges of PFAS Extraction
The automation for PFAS extraction is more demanding than other SPE methods, due to the complex extraction steps (including sample bottle rinsing), low background requirements and range of compound behavior.
In July 2018, we developed the MOD-004 automated sample bottle rinsing function and MOD-005 minimal-Teflon option for the SPE-03. Close collaboration with laboratories from the United States and Australia has resulted in a well-accepted solution that is fully automated, fast, clean, and robust. The below article featured on SelectScience showcases our development efforts with Merit Labs on our first PFAS system for EPA Method 537.
