Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
The Focus LC® separated PAHs in ~12 and ~15 min, with separate methods on short capillary columns packed with 1.7 µm monomeric and 3.0 diameter polymeric C18 particles.
