PFAS Acronyms: It’s hard to know the players without a scorecard
Many of the longer chain carbon compounds analyzed as part of PFAS testing have long chemical names and can be tricky to differentiate. At Merit Laboratories, we’re always working to find ways to make it easy for our clients. To help you out, here’s a list of acronyms used for commonly-analyzed polyfluoroalkyl substances (PFAS).
