This webinar highlights sample preparation and chromatography contributions in LC-MS/MS workflows for PFAS and GenX compounds.

While per-and polyfluorinated alkyl substances (PFAS) continue to persist throughout the environment, additional interest is expanding to short chains, branched isomers, and PFAS replacement compounds, such as GEN-X mixtures.  Among the difficulties of analysing trace levels of these ubiquitous compounds, we cover some extraction solutions from more complicated matrices.  We also review how column chemistry can help improve retention of the shorter acids, while maintaining selectivity throughout the aliphatic range along with branched isomers and GEN-X.

  • Apply particle morphology and column chemistry contributions for HPLC and UHPLC workflows
  • Apply the appropriate sample preparation technique to meet different compound ranges and sample matrices, including Solid Phase Extraction, QuEChERS, and dual layered sorbents
  • Reduce PFAS background
