Per- & Polyfluoroalkyl Substances (PFASs)

In the late 1940s, 3M pioneered the discovery and manufacturing of PFASs through an electrochemical fluorination process that was used until 2001. This process generates a complex mixture of even- and odd- numbered carbon chain lengths. The amphiphilic ability of PFASs have led to the manufacturing of PFASs in oils and water-resistant industrial and consumer products such as firefighting foams, cleaners, cosmetics, paints, adhesives and insecticides.

However, environmental chemists and biologists have uncovered that PFASs have harmful toxicolgical effects and pose a significant risk to the public. Perfluorooctanesulfonic acids (PFOSs), the key ingredient in fabric protectors and stain repellants, was the first perfluorinated compound to be added to the Stockholm Convention on Persistent Organic Pollutants in 2009.

The high thermal and chemical stability of PFASs make them persistent in the environment and nearly non-biodegradable, necessitating chemical reference standards to test the validity and concentration of PFASs in drinking water, burn sites and teflon products

AccuStandard offers the 14 component standard mixture associated with EPA method 537 (Determination of selected perfluorinated alkyl acids in drinking water analyzed by LC/MS/MS) and the extended 24 component mixture. Single neat and solution PFCs are also available.
