Ultra high-purity activated carbon
Delay Column for PFAS Installation Position
Chromatogram Using Delay Column for PFAS
The Delay column for PFAS is packed with high purity activated carbon beads, which strongly retain the background PFAS from the LC system and mobile phase. The retained PFAS compounds are eluted with 100% acetonitrile, allowing a greater separation from the analytes on the chromatogram.
Delay Column for PFAS Effect
A general C18 column is commonly used as the delay column in the analysis of PFAS. When a general C18 column is used, it only shows a small delay and insufficient isolation. When GL Sciences Delay column is used as shown below, better separation is obtained.
Comparison of System Pressure using Delay Column for PFAS
Delay Column for PFAS does not increase the LC system pressure.
