Capillary columns, PLOT
Aluminum oxide PLOT columns offer high selectivity for separating ppm levels of C1 to C5 hydrocarbons in a main stream of C1 to C5 hydrocarbons.
- High analytical capacity improves efficiency
- No need for sub-ambient cooling simplifies operation
- Choice of two polarities for a broad range of applications
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-Al₂O₃ PLOT column offers increased selectivity and allows all C1 to C5 hydrocarbon isomers to be separated.
Aluminium oxide PLOT columns are deactivated using very small salt crystals, providing a reproducible and stable deactivation up to 200 °C. Depending on the type of deactivation salt, the CP-Al₂O₃ PLOT column will show a particular selectivity. The KCl salt results in a relatively apolar Al₂O₃ surface, while Na₂SO₄ deactivation provides a polar surface. Unsaturated compounds such as ethylene and acetylene (ethyne) are retained longer.
