In this video, Prof. Detlef Knappe, from North Carolina State University, shares his work analyzing contaminants in drinking water. Knappe outlines the analytical methods used to identify and assess contaminants, including per- and polyfluoroalkyl substances (PFASs), to understand routes of contamination and determine the safety of drinking water. Knappe also highlights how Agilent supported the development of these analytical methods.
