Polar-deactivated guard/retention gap columns are tested with a comprehensive test mix to ensure high inertness.

• Polar polyethylene glycol deactivation
• High degree of chemical inertness
• Compatible with Stabilwax®, Rtx®-225, and Rt®-2330 capillary columns
• Maximum temperature: 280 °C
• 30-meter lengths are banded in 5-meter sections

Polyethylene glycol deactivation layer provides optimum wettability for polar compounds. Minimize peak splitting when using polar solvents such as methanol or water.
