Per- and polyfluorinated alkyl substances (PFAS) are highly stable industrial compounds that persist in the environment and are frequently detected in water, soil, and biological samples. Because of their chemical resistance, PFAS materials are commonly used in HPLC system components such as tubing and other liquid-contact parts. Over time, these components can release trace amounts of PFAS into the mobile phase, creating background contamination that affects analytical accuracy—particularly when laboratories are testing at very low ppt or sub-ppt levels.
Restek’s PFAS delay column is specifically developed to solve this problem. It works by trapping and delaying system-related PFAS contamination before it reaches the analytical column, preventing interference with target compounds. This allows laboratories to achieve more accurate identification and quantitation, especially in sensitive applications like drinking water testing and environmental monitoring.
Designed as a universal solution, the PFAS delay column is compatible with all HPLC and UHPLC systems operating up to 15,000 psi (1034 bar). It can be used with any analytical column, including fully porous or superficially porous formats.
