Which GC Liner Should I Use?

The Agilent GC liner isolates the sample-flow path from the metal walls of the injector block. Variable GC inlet liner geometry and packing materials characterize sample volatilization. Proper inlet liner selection is crucial to ensure all analytes of interest are rapidly vaporized and transferred to the analytical column without unanticipated interactions or degradation resulting in inlet discrimination.

Dimpled Liners for GC

  • Used in the Agilent Multimode Inlet (MMI) when analyzing heavy matrix.
  • Optimized for cold splitless injections and solvent vent injections.
  • Not recommended for hot injection because of the small internal volume.

Ultra Inert Inlet Liners Advantage

  • All recommended liners on this page are Ultra Inert
  • Ultra Inert liners feature a proprietary deactivation process.
  • Eliminate potential active sites located throughout the interior of the liner.
  • Facilitates the reliable analysis of trace and active analytes without unintended inlet discrimination.
