column for separing HCL from pure Hydrogen

[tigerk2001]

Hi,
Can you help me to configure my GC for the separation of HCL(10ppm) from pure Hygrogen. What is the best configuration and column to use with a Helium DID.
I normally work with packed columns.
References or chromatograms would be great
Thanks for your help.

How is the analyzer business? You must be in a hurry if you seek not only the application design but chromatograms as well.

Are you offering a cut for the development of the application?

I would have thought that you could design this application yourself. Almost any and every column packing will separate H2 and HCl. Even more important that the packing material is the column material as your matrix is probably pretty warm. If any water is present you will have a very corrosive mix in your sample lines and sample valve.

Be glad your HCl is not HF. That is a real stinker of an analyte to deal with.

Hi George,
You're right, I'm in hurry. I'm quoting a system for separation of o2-Ar-n2-ch4-co-co2-h20-hcl all in a range of 0-10ppm in pure hydrogen. I can easily deal with the other impurities but I have no experience with HCL specially since 10ppm moisture is in the sample.
Can you please help giving a configuration for hcl?
As usual , your support is greatly appreciate
thanks

If you are not measuring water or HCl then backflush them both.

At those concentrations a porous polymer or FFAP on Carbon should work well for a backflush.

Good luck,
