Per- and polyfluorinated alkyl substances (PFAS) represent a class of synthetic compounds that have gained significant attention due to their widespread use and environmental persistence. Known for their toxicity PFAS pose serious challenges to both public health and the environment making effective testing essential. The United States Environmental Protection Agency (US EPA) has established several guidelines for PFAS testing regulations emphasizing the need for rigorous analytical methods.
