Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
Phospholipid removal proves to yield superior results as compared to a traditional protein precipitation step when analyzing a complex plasma matrix via LC–MS-MS. The results displayed a decrease in ion suppression, increased analyte sensitivity, and an improvement in column lifetime.
