The ability to collect compounds is directly related to the ability to detect them. Many compounds possess weak or non-existent chromophores which causes UV detection to exhibit poor yields.
Automated PFAS Extraction from Difficult Food and Food Packaging Samples
December 6th 2024More and more regulations regarding PFAS are being implemented with action limits that continue to decrease. Having a harmonized method to accurately determine the PFAS content in food, as well as other matrices, is important to ensuring long-term detection and regulation. The solvent extraction of PFAS from these varied sample matrices can be challenging given the susceptibility to contamination and the low levels in which these compounds are present. This poster, presented at RAFA 2024, examines the PFAS extraction several different food samples as well as food packing matrices.
Extraction of 40 PFAS Compounds from Soil and Tissue
December 6th 2024PFAS 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.
