What kind of column and stationary phase are suitable for detecting carbon dioxide?
The TDX-01 packing column will do
It depends on which component of carbon dioxide you want to analyze. For example, using a silica gel column (HDG201) to analyze carbon dioxide in air or sulfides in carbon dioxide, etc. The TDX-01 column can separate oxygen, nitrogen, carbon monoxide, carbon dioxide, etc
It’s hard to say; one needs to have a general understanding of the entire system being analyzed (such as its main components) in order to choose the appropriate chromatographic analysis conditions.
Are you trying to analyze the purity of carbon dioxide, or the trace amount of carbon dioxide in the gas? ? These two are different. If it’s about the purity of carbon dioxide, chemical analysis is sufficient; there are specialized instruments for measuring purity. If it’s about the carbon dioxide content in other gases, a TDX-01 column is sufficient
