GS-Alumina

Agilent J&W GS-Alumina is the most polar alumina phase. The phase consists of aluminum oxide with proprietary deactivation. GC-Alumina is an excellent general use column for light hydrocarbon analysis, with C1 to C8 hydrocarbon isomers. Alumina columns have a tendency to adsorb water and CO2 which, over time, result in changes in retention time. Agilent uses an advanced, proprietary deactivation process that allows for rapid regeneration, and so fully moisture saturated GS-Alumina columns regenerate completely within 7 hours or less at 200 °C.

• Most "polar" Alumina phase
• Aluminum oxide with proprietary deactivation
• Excellent general use column for light hydrocarbon analysis: C1 to C8 hydrocarbon isomers
• Separates C1 to C4 saturated and unsaturated hydrocarbons
• Best for resolving cyclopropane from propylene
• Faster, more efficient and provides more sensitivity than packed equivalents
• Preferred substitution for sodium sulfate deactivated Alumina because of its regnerative nature
• Minimal conditioning time required
• Each Agilent J&W GC column is tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency to provide you utmost confidence in qualitative and quantitative results
• For details about the QC test conditions including the test probe mixture and the resulting chromatogram, please refer to the Agilent J&W GC Column Performance Summary shipped with each GC column

Note: Alumina columns have a tendency to adsorb water and CO2 which, over time, results in changes in retention time. We use an advanced, proprietary deactivation process which allows for rapid regeneration. Fully water saturated GS-Alumina columns regenerate in 7 hours or less at 200 °C.
