Base-Deactivated Fused Silica Guard/Retention Gap Columns

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

Tested with a basic amine test mix.
Excellent inertness for basic compounds.
Recommended for use with Rtx®-5 Amine, Rtx®-35 Amine, and Stabilwax®-DB capillary columns.
Batch test chromatogram included.
Maximum temperature: 315°C.

Chemists using guard columns in analyses of basic compounds frequently observe peak tailing and low recovery. This happens because conventionally deactivated tubing surfaces can be adsorptive to basic compounds. Restek offers base-deactivated guard columns for completely inert sample pathways.
