Polar Deactivated Fused Silica Guard/Retention Gap Columns

Use guard columns to:
• Reduce effects of dirty samples on column performance.
• Reduce downtime and maintenance.

Polyethylene glycol deactivation layer provides optimum wettability for polar compounds.
Minimize peak splitting when using polar solvents such as methanol or water.
Compatible with Stabilwax®, Rtx®-225, and Rt®-2330 capillary columns.
Maximum temperature: 280°C.

Tested with the Grob test mix, to ensure high inertness.
