Detection of trace amounts of ammonia in acetonitrile?
Thread Content
I heard that the Nessler’s reagent colorimetric method can be used to detect ammonia, and after checking, it is mostly used for measuring ammonia in aqueous solutions and urea. No ammonia content was detected in the solvent? Has anyone done any related experiments? In the experiments I conducted, the ammonia content in acetonitrile was underestimated; manually measuring it would likely result in larger errors. Is there any equipment that can do it? (I only found products for measuring ammonia in gases in the market) :)
