Introduced the characteristics and uses of GS-OxyPLOT column
The Agilent GS-OxyPLOT is a porous layer open tubular (PLOT) column featuring a proprietary, salt-deactivated adsorbent stationary phase. It offers high chromatographic selectivity specifically for low molecular weight oxygenated hydrocarbons and serves as an appropriate replacement for Varian's CP-LowOx column.
The document provides technical specifications including temperature limits (0 °C minimum, 350 °C maximum oven program), conditioning instructions, and sample loading limitations. It lists specific ASTM methods the column is designed for and provides a table of suitable oxygenated compounds such as methanol, ethanol, and various ethers and aldehydes.
| Stationary Phase Type | proprietary, salt deactivated adsorbent |
|---|---|
| Minimum Temperature Limit | 0 °C |
| Isothermal Maximum Temperature Limit | 300 °C |
| Oven Program Maximum Temperature | 350 °C |
| Conditioning Temperature | 300 °C for at least 3 hours |
When first installed, the column should be conditioned at 300 °C for at least 3 hours.
It is recommended to set the GC oven to an isothermal temperature of 220 °C with normal carrier gas flow when the column is installed but idle.
Injection should be limited to organic compounds with 11 carbons or less to prevent the column from fouling.
