Agilent CP-Al₂O₃/NA₂SO₄ Capillary GC Columns

Agilent J&W CP-Al₂O₃/Na₂SO₄ is an aluminum oxide PLOT column that offers high selectivity for separating ppm levels of C1-C5 hydrocarbons in a main stream of C1-C5 hydrocarbons. The Na₂SO₄ deactivation salt provides a polar Al₂O₃ surface, so that unsaturated compounds such as ethylene and acetylene are retained longer. 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, CP-Al₂O₃ provides increased selectivity and allows all C1-C5 hydrocarbon isomers to be separated. CP-Al₂O₃ operates without the need for sub-ambient cooling.
