Investigating Fluorine Compounds in Non-Aqueous Samples
Alongside the high priority to understand the environmental and health impacts of PFAS, companies are working very hard to limit new PFAS compounds from entering the environment and new state-by-state regulations are being enacted beyond water. State-level action on PFAS accelerated starting in 2021, with many laws introduced to ban certain products and packaging containing the compounds.
Common analytical methods such as Parr™ Bomb or X-ray fluorescence (XRF) present challenges due to long analysis times and interference from other additives. Parr Bomb measurements lack accuracy and precision, typically requiring samples to be run in triplicate to achieve meaningful analysis. XRF is more accurate, but subject to interference from other polymer components and lack of sensitivity at low concentrations.
Combustion Ion Chromatography (CIC) is being used as an effective tool for releasing fluoride from samples like carpet fibers and plastics.
