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 Note shows the transfer of an analysis method for anti-epileptic drugs from HPLC to UHPLC using the Agilent 1290 Infinity II LC system. An enormous time and solvent saving of approximately 95 % was achieved with an UHPLC separation optimized for speed.
