  • Understanding Ammonia Analysis Methods from Cole-Parmer

    IntroductionApproved MethodsMethod ProcedureAmmonia (NH3) is one of the many form’s nitrogen takes as it makes its way through the environment. In high enough concentrations, it is toxic to fish and everyone is aware of the unpleasant odor it spreads. In nature ammonia occurs from the decomposition of organic compounds that contained nitrogen (almost all of them) or the hydrolysis of urea (the compound that gives urine its name). Generally speaking, natural sources of ammonia are dispersed far and wide enough that we would never notice it. However, if enough of those natural sources of ammonia are concentrated into one stream (a sewer) it can become a problem in the water source.
