Help quantifying NH3

[nfrankE3]

Hi,

My name is Nicholas Frank and I am a development engineer at E3 Clean Technologies. We have a product which produces ammonia and other gaseous compounds. We are in the development stage of this product and need the effluent gas stream quantified. So far, we have been able to identify ammonia, carbon dioxide, nitrogen, oxygen and hydrogen in our effluent gas stream. But we've only been able to identify these compounds, not quantify them.

We would like to quantify these compounds and finding a vendor to which we send samples is proving difficult. This is mostly because of ammonia. Our product exists to produce ammonia, so obviously there are very high concentrations (>10%). Most vendors cannot quantify ammonia and/or it damages their GC equipment.

I am aware of the OV-1 column which can quantify ammonia and was wondering if anyone had access to a GC or knew someone who did, who can quantify our effluent gas stream?

Thanks for your time.

GC is not the only method to analyse gases.
Google for ammonia gas analyser. You will find a lot of online gas analysers.

Hi,

Thanks for the response dblux. We are not only interested in the ammonia content, we would like the entire effluent gas stream quantified. If there are other methods of doing this then we are open to suggestions for them as well.

nfrankE3,

You can do ammonia by either HID (helium ionization detector) or AID (argon ionization detector) on GC. It has a low enough IP that it will be easily measureable on AID. There are some issues to be aware of. 1) Bulk level ammonia will be difficult to introduce at low enough levels to be linear (probable solution there is very small valve injection volume.) 2) What else do you want to measure since column selection will get interesting depending on this answer? 3) How much water is present since this will wreak havoc?

Do you want to set this up or do you want someone else to do the analysis?

Feel free to contact me if you want to discuss further. aicmm at flash dot net.

Best regards,
