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. The updated 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 (λex/em = 415/475nm) is proportional to the ammonia concentration in the sample.
Applications :
For quantitative determination of ammonia and ammonium in biological samples.
Storage :
