Laboratory derived PFAS interferences from commonly encountered supplies and equipment

Per- and polyfluoroalkyl substances (PFAS) comprise a large number of substances that occur in a broad range of applications and products. PFAS are of concern because of their high persistence and impacts on human and environmental health. PFAS pose particular challenges in the analytical laboratory as they are present in common consumables and hardware. EPA Method 533 stipulates laboratories must demonstrate supplies and equipment are not contributing PFAS interference, leading to elevated minimum reporting levels. We present a study of PFAS residues in commonly encountered laboratory supplies and equipment to highlight potential sources of laboratory derived PFAS interferences.
