GS-Alumina

GS-Alumina PLOT GC Columns from Agilent Technologies

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.

Agilent J&W GS-Alumina KCI is the least polar PLOT alumina phase and is made from aluminum oxide, with proprietary deactivation. GS Alumina KCI is a good choice for light hydrocarbon analysis.

GS-Alumina GC Columns

Agilent J&W GS-Alumina is the most polar alumina phase and is an excellent general use column for light hydrocarbon analysis.

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

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.
