Aluminum oxide columns are specifically designed for detailed C1-C10 hydrocarbon analysis in chemical and petrochemical industries. Due to the high selectivity of CP-Al2O3 PLOT columns, it is possible to analyze ppm to percent levels of any C1-C5 impurities, including isomers, in main stream C1-C5 products. CP-Al2O3 PLOT columns offer a higher level of analytical selectivity and efficiency compared to super-thick film non-polar liquid stationary phase columns.
This document describes the use of the Agilent CP-Al2O3/Na2SO4 PLOT GC column for the detailed analysis of C1-C5 light hydrocarbons. The column features a sodium sulfate deactivation layer that provides stable selectivity up to 200 °C and retains unsaturated compounds more strongly than potassium chloride-treated alumina.

The sodium sulfate deactivation provides a reproducible and stable selectivity up to 200 °C.
The column retains unsaturated compounds such as ethylene, acetylene, and methyl acetylene more strongly than their saturated peers.
The analysis is performed using the GC-FID technique.
