Rxi Capillary GC Guard Column 5m x 0.53mm

The Restek Rxi Guard Columns extend lifetime of the capillary columns and improve peak shapes of the analytes. As can be seen from the Rxi abbreviation (Restek eXtreme Inertness), the surface deactivation technology effectively shields silanols and ensures comprehensive inertness for polar compounds as well as acids and bases, resulting in symmetric and sharp peaks, higher sensitivities and lower detection limits.
