Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
A separation of ultra-short and long chain PFAS (C1-C18) is performed on a HALO®PCS Phenyl-Hexyl column along with a HALO®PFAS Delay column which demonstrates excellent retention for both hydrophilic and hydrophobic analytes.
