## Main Question or Discussion Point

What is a cost efficient, yet accurate way to detect ammonia in a gaseous mixture?

Ammonia fumes react with HCl fumes and make a white smoke of ammonium chloride. Accuracy depends of the mixture, I guess.

Those Draeger tubes look like a viable solution, though it is a bit pricey for home use. The pump looks to be $600 for the cheapest version then$70 per test for the tubes.
