Guard Column Base deactivated, 5 m, 0.25 mm ID

Base-Deactivated Guard/Retention Gap Columns (fused silica)

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

Chemists using guard columns in the 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, as well as base-deactivated inlet liners, for completely inert sample pathways.
