Novel per- and polyfluoroalkyl substances in an active-use C6-based aqueous film forming foam

Journal of Hazardous Materials Letters, 2022
Studies have identified hundreds of per- and polyfluoroalkyl substances (PFAS) in aqueous film forming foam (AFFF) using high resolution mass spectrometry (HRMS), and there is increasing reliance on HRMS with suspect screening in areas such as PFAS fate ...

Machine Learning for Absolute Quantification of Unidentified Compounds in Non-Targeted LC/HRMS

Molecules, 2022
LC/ESI/HRMS is increasingly employed for monitoring chemical pollutants in water samples, with non-targeted analysis becoming more common. Unfortunately, due to the lack of analytical standards, non-targeted analysis is mostly qualitative. To remedy this,
