Liquid chromatography–ion mobility spectrometry–high-resolution mass spectrometry (LC–IMS–HRMS) shows elephant seal pups carry more PFAS than their mothers do.
The HALO® OLIGO C18 2.7 µm column outperformed an FPP Oligo C18 column in oligonucleotide separations, achieving faster separations while maintaining efficiencies comparable to a 1.9 µm FPP with more than half the backpressure.
