Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
An understanding of analyte hydrodynamic radius (Rh), as well as size exclusion column pore size and distribution, are all critical in the understanding of how an analyte will behave by SEC. In this white paper, we will explore several protein standards with known hydrodynamic radii, and how this can be used to determine ideal size exclusion conditions for optimal method performance.
