Analysis of chlorine gas

Oxygen and water contained in chlorine should also be analyzed.
For impurity gases in chlorine, it is necessary to analyze the presence of hydrogen, nitrogen, water, etc., in chlorine. Hydrogen in chlorine and nitrogen in chlorine can be analyzed using gas chromatography or an Ossietzky gas analyzer, while water content is determined by absorbing it with phosphorus pentoxide and then weighing it.
I would like to ask everyone: when analyzing impurity gases in chlorine, which brand of gas chromatograph is better?
I think Agilent models are good; the 6820 or 6890 are both fine
Using chromatography for chlorine can easily lead to clogging ··
Impurity analysis includes: hydrogen, oxygen, nitrogen, and water content. For the detection of water content in chlorine, an online analyzer is recommended. When using chemical analysis methods, the analysis results are greatly influenced by the environment as well as human factors.
It is also necessary to analyze that the water content must be less than 0.03%
I exactly need information in this area. Thank you for sharing
