New Dimension in Chromatography - Halo® 1.5



HALO® PFAS Delay is an application assured column solution. The delay column is used to prevent background PFAS contamination from interfering with the PFAS of interest that are separated with the analytical column. The delay column bonded phase is a highly retentive endcapped silane chosen for its ability to demonstrate delay of background instrument PFAS contamination across multiple mobile phase conditions. For this reason, the HALO® PFAS Delay column is placed upstream of the sample injector.
