Evaluation of Extraction Options for EPA Draft Method 1633

Abstract:

EPA Draft Method 1633 provides a standardized approach for measuring up to 40 PFAS in a diverse range of environmental matrices. This method demands a two-step sample prep approach that adds a clean-up step, but this has practical limitations, is labor intensive, and could interfere with lab workflow and sample throughput. To streamline this process, Strata™ PFAS cartridges were developed as a single cartridge stacked with Strata-X-AW and Strata GCB sorbents that function as a traditional SPE cartridge with a built-in polishing step to meet the method guidelines. This technical note presents a study to validate method performance for the broader compound list in EPA 1633 and demonstrate the same utility for both water and soil extracts when using Strata™ PFAS solid phase extraction cartridges for sample prep.
