Selectra® PFAS Delay Column, 50 x 4.6 mm, 5 µm, ea

Achieve cleaner, more reliable PFAS data with UCT’s Selectra® PFAS Delay Column. Installed before the injector, it captures background PFAS from LC system components and solvents, shifting them to later retention times. This prevents interference with target peaks, reduces false positives, and ensures confidence at ultra-trace detection levels. Fully QC tested and compatible with C18 and PFPP chemistries, the Selectra® PFAS Delay Column is a simple, powerful solution for accurate PFAS analysis.
