PFAS (Per- and poly-fluoroalkyl substances) are persistent, man-made organic compounds, widely found in the environment. Recent awareness about their toxicity has led the U.S. Food and Drug Administration (FDA) and the U.S.
Environmental Protection Agency (EPA) to initiate actions against PFAS. Hence reliable and fast methods for their determination are needed.

PFASs are commonly measured using liquid chromatography–mass spectrometry (LC-MS). The column of choice for PFAS analysis by LC-MS(/MS) is a C18 column. The Ascentis® Express PFAS columns are based on superficially porous silica particles (SPP) with C18 modification and are specifically tested using a PFAS compound mixture. This ensures the suitability and reliable performance of these columns for an efficient PFAS analysis.
