Agilent GS-Alumina Capillary GC Columns
By Agilent Technologies
- Most "polar" Alumina phase
- Aluminum oxide with proprietary deactivation
- Excellent general use column for light hydrocarbon analysis: C1 to C8 hydrocarbon isomers
- Separates C1-C4 saturated and unsaturated hydrocarbons
- Best for resolving cyclopropane from propylene
- Faster, more efficient, and provides more sensitivity than packed equivalents
- Minimal conditioning time required
- Preferred substitution for sodium sulfate deactivated Alumina because of its regenerative nature
Note: Alumina columns have a tendency to adsorb water and CO2, leading to changes in retention time. An advanced, proprietary deactivation process allows for rapid regeneration. Fully water-saturated GS-Alumina columns regenerate in seven hours or fewer at 200°C.
