For my third post in this series, I would like to focus on specialty packed columns for hydrocarbon analysis. In some cases, the packings in these columns are proprietary, so detailed information cannot be provided. In other cases, application information may be limited. However, we can provide maximum temperature limits (see table below).
For other columns used for hydrocarbon analysis, you should be able to find the maximum packing temperature based upon the maximum temperature of the liquid phase(s) and/or the porous polymer(s).
If there is a packed column for hydrocarbon analysis that is sold by Restek and not included in this table or in either link above, contact Restek. Thank you.
| Column and/or Packing | Max Temp (°C) |
|---|---|
| D3606 Packed GC Column Set | 150 |
| 0.19% picric acid on CarboBlack C | 120 |
| 23% Rt-1700 on Chromosorb PAW | 110 |
| n-Octane on Res-Sil C | 150 |
| OPN on Res-Sil C | 150 |
| 2abc Refinery Gas Column Set | 110/200* |
| Alumina F-1 | 300 |
| Rtx-1 SimDist 2887 | 350 |
*While this column is capable of 200 °C, it is designed for isothermal analysis at 110 °C.
