We have developed and optimized several PFAS extraction workflows, including water, sediment, soil (regular and AFFF-impacted), landfill leachate, biosolids, gas condensate, gas emissions, street sweepings, road dust, product leachate, house dust, biological tissue, blood-based matrices, and food. We have our own optimized methodologies (see below), though we also use readily available workflows (e.g., EPA 1633), depending on the needs of each project.  We are always trying to improve our workflows and are always open to new matrix-based challenges and/or collaborations.
