SH Guard Column Polar Deactivation, 30m, 0.25mm, 0.37mm OD

Part No.: 227-36334-01

Tested with a basic amine test mix. Excellent inertness for basic compounds. Recommended for use with SH-5 Amine, SH-35 Amine, SH-Volatile Amine, and SH-PolarX 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. Shimadzu offers basedeactivated guard columns, as well as base-deactivated inlet liners, for completely inert sample pathways.
