一般描述
Ascentis® Express PFAS Delay is a high-performance liquid chromatography column based on Fused-Core® particle design. The highly retentive endcapped silane of the Ascentis® Express PFAS Delay column provides high retention of PFAS compounds across various mobile phase conditions and is used to delay background instrument PFAS contamination from interference with analyzed samples. For this reason, the Ascentis® Express PFAS Delay column is placed upstream of the sample injector.
