GC COLUMNS
Fused Silica Guard/Retention Gap Columns
Polar-Deactivated Guard/Retention Gap Columns (fused silica)
(polar polyethylene glycol deactivation)
• Tested with a comprehensive test mix to ensure high inertness.
• 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.
*30-meter lengths are banded in 5-meter sections.
To eliminate connections, use an
Integra-Guard® column. (See )

Intermediate-Polarity Deactivated Guard/Retention Gap Columns/
Transfer Lines (fused silica)
• Tested with a comprehensive test mix to ensure high inertness.
• Useful for a wide range of applications.
• Use with most common solvents.
• Maximum temperature: 325 °C.
*30- and 60-meter lengths are banded in 5-meter sections.
†Recommendation: Cut 60 m guard columns into shorter lengths. Using full length may cause peak distortion.
