Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
This application is an alternative HPLC method for the analysis of 13 carbonyls without the use of any derivatization agent. The method uses the combined polar and non-polar selectivity of a Kinetex Biphenyl stationary phase to achieve improved chromatographic results.
