Wednesday, June 1st, 2022 at 2pm EDT|11am PDT|7pm BST|8pm CEST As more PFAS compounds are discovered and more complex matrices are tested, both regulated and unregulated analytical methods will need to adapt. This webinar will show the benefits of alternative workflows, such as high-resolution mass spectrometry and other screening techniques, to ensure the proper identification of PFAS compounds while providing quantitative results. It will also address the modification of the stationary phases of varying surface chemistry and eluents of varying polarity, which causes the sorption-elution characteristics of different classes of PFAS compounds to be altered.
