CP-Al2O3/Na2SO4 

Aluminum oxide PLOT columns offer high selectivity for separating ppm levels of C1-C5 hydrocarbons in a main stream of C1-C5 hydrocarbons. These columns analyze more compounds in a single run than packed columns, while still delivering higher resolution and faster analysis times. When compared to liquid stationary phases, the CP-Al203 PLOT Column offers increased selectivity and allows all Cl-C5 hydrocarbon isomers to be separated. CP-Al2O3 operates without the need for sub-ambient cooling and is available in two unique selectivities.
