Rationale

With recently found ultrashort-chain PFAS (C1 - C4) in the environment especially with rainfall and snowfall, reversed phase LC separation may not have proper retention or provide good peak shapes for these early eluting PFAS analytes. Having only one MRM transition can be a challenge in confirmation of those analytes due to uncertainty coming from background interferences. Adopting existing LC-MS/MS technology with two complementary chromatography for confirmation of these analytes are necessary.
