Use of Thermo Scientific Exploris 120 Orbitrap HRAM-LC-MS for analysis of 47 PFAS compounds in UK waters

John Quick from ALS Environmental introduces a method designed using high-resolution mass spectrometry (MS) on the LC Orbitrap™ system for studying 47 PFAS compounds in UK waters. Quick discusses his team's methodology using the Thermo Scientific™ Orbitrap™ Exploris™ 120, presenting an extraction method based on EPA 1633, and achieving limits of detection of <1ng/l for all compounds with good precision and bias. See how high-resolution MS provides scope for advancement in targeted and untargeted PFAS screening methods.
