Poly- and perfluoroalkyl substances, or PFAS, are rapidly emerging as some of the most important environmental contaminants to monitor around the world. Their widespread use and environmental persistence make them truly a global issue. Concerns about possible health risks are driving environmental scientists to look for these compounds everywhere. However, one other concerning place where at least some of these compounds are present is inside the very instruments used for PFAS analysis of environmental samples. PFAS delay columns can be used to manage this type of contamination.
