GAS-PHASE DETECTION OF FLUOROTELOMER ALCOHOLS AND OTHER OXYGENATED PER- AND POLYFLUOROALKYL SUBSTANCES BY CHEMICAL IONIZATION MASS SPECTROMETRY
Riedel, T., J. Lang, M. Strynar, A. Lindstrom, and J. Offenberg.
Environmental Science & Technology Letters 6(5):289-293(2019)
Chemical ionization mass spectrometry with iodide reagent ion chemistry was evaluated for the detection of fluorotelomer alcohols (FTOHs) and other oxygenated PFASs, including per- and polyfluoro carboxylic acids, such as hexafluoropropylene oxide dimer acid. Measurements were taken by direct volatilization of samples without prior processing, which allowed for fast measurements and reduced sample treatment compared to established PFAS methods. The utility of this technique was validated by sampling volatile and semivolatile PFASs from fluoro additives and fluoro products to quantify levels of FTOHs and identify additional fluorinated compounds for which standards were unavailable. https://doi.org/10.1021/acs.estlett.9b00196
