Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
This method presents the reversed-phase retention and detection of 7 polar Neonicotinoids and 4 deuterated-internal standards by LC-MS/MS and with a Kinetex 2.6 Biphenyl HPLC column. The Kinetex Biphenyl phase demonstrated significant polar compound retention and selectivity.
