The column of choice for light hydrocarbons, and for the quantification of dienes.

• Least polar alumina phase
• Aluminum oxide deactivated with KCl
• Low retention of olefins relative to comparable paraffin
• Recommended phase for many ASTM methods
• Preferred KCl deactivated alumina
• Similar phases: Rt-Alumina PLOT, Alumina PLOT, Al₂O₃/KCl, AB-PLOT Al₂O₃/KCl, AT-Alumina

Agilent J&W HP-PLOT Al₂O₃ KCl is the least polar alumina phase and is deactivated with sodium chloride. It is the standard column choice for light hydrocarbon analysis, particularly C1 to C8 hydrocarbon isomers. Excellent for the quantification of dienes, especially propadiene and butadiene from ethylene and propylene streams.
