GC COLUMNS | CAPILLARY COLUMNS
Fused Si l ica Guard/Retent ion Gap Columns
*30- and 60-meter lengths are banded in 5-meter sections.
†Recommendation: Cut 60m guard columns into shorter lengths. Using full length may cause peak distortion.
Polar-Deactivated Guard/Retention Gap Columns (fused silica)
• 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.
Siltek®-Deactivated Guard/Retention Gap Columns/Transfer Lines
(fused silica)
• Tested with a comprehensive test mix, to ensure high inertness.
• Revolutionary deactivation process for superior inertness.
• Analyze active samples accurately; ideal for chlorinated pesticide analysis
(reduces endrin breakdown to less than 1%).
• Maximum temperature: 380 °C.

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
Rxi® Guard/Retention Gap Columns (fused silica)
• Extend column lifetime.
• Excellent inertness—obtain lower detection limits for active compounds.
• Sharper chromatographic peaks by utilizing retention gap technology.
• Maximum temperature: 360 °C.

did you know ?
Siltek®-deactived guard columns minimize
breakdown and improve recovery of analytes!
Use guard columns to:
• Reduce effects of dirty
samples on column
performance.
• Reduce downtime and
maintenance.
