PFAS have been shown to cause health issues in humans, which means monitoring environmental solid samples, such as soil and tissue, is critical. This application note details the extraction of 40 spiked PFAS compounds from soil and tissue following EPA Method 1633. The automated extraction was less than 10 minutes per sample and yielded acceptable recoveries and RSDs without carryover in the system. The EDGE PFAS is an ideal option for laboratories that want to automate their PFAS extractions of solid samples.

Existing solvent extraction techniques are predominantly manual methods that are not rapid, simple, or efficient. The EDGE PFAS™, an automated solvent extraction system, provides an automated, sequential approach to PFAS extraction. This system performs an efficient extraction of PFAS compounds from challenging food and food packaging matrices in one simple process. Upon completion, the final extract is filtered and ready for any minimal cleanup required, as well as analysis. Excellent recovery with tight reproducibility has been found. The EDGE PFAS method offers a rapid, simple, and efficient solvent extraction solution for PFAS testing.
