Detecting Ammonia

    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.

    The reason I am asking is I am wondering, with the application of selective catalysts to vehicles throughout Europe and the US, if there is a cheap way for the home mechanic to determine the efficiency of the urea injectors. $650 for a troubleshooting tool is too much for that purpose.
