Maximum temperatures of packed columns – Sulfur Gases

For my fifth and final post in this series, I would like to focus on packed columns for light sulfur gases.  Compounds include (but not limited to) hydrogen sulfide, sulfur hexafluoride, carbonyl sulfide, sulfur dioxide, methyl mercaptan, ethyl mercaptan, etc.

Because some analysts prefer PTFE tubing and/or PTFE frits for their columns, the maximum temperature may be limited to this hardware (which is 200°C).

If the columns below are in SilcoSmooth tubing, their maximum temperatures are shown below.

	Max Temp
Column and/or Packing	(°C)
Rt-XLSulfur	290
1.5% XE-60 / 1% H3PO4 on CarboBlack B	250
Chromosorb T	250
