Ammonia (NH3) or its ion form ammonium (NH4+) is an important source of nitrogen for living systems and is ubiquitously present in the nature. Simple, direct and automation-ready procedures for measuring NH3 are very desirable. Ammonia/ammonium assay is based on an improved o-phthalaldehyde method. This reagent reacts with ammonia/ammonium and forms a fluorescent product. The fluorescence intensity (lex/em=360/450nm) is proportional to the ammonia concentration in the sample.
Key Features:Fast and sensitive: Linear detection range of 0.012-1mM ammonia
Convenient and high-throughput: Homogeneous "mix-incubate-measure" type assay. Can be readily automated on HTS liquid handling systems for processing thousands of samples per day.
Applications:Ammonia/ammonium determination in biological (e.g. urine) and environmental samples.
