For quantitative fluorometric determination of ammonia/ammonium concentration.

• Linear detection range of 0.012 - 1 mM ammonia
• Can be readily automated to process thousands of samples per day

Ammonia (NH3) or its ion form ammonium (NH4⁺) is an important source of nitrogen for living systems and is ubiquitously present in the nature

BioAssay Systems’ 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 = 360/450nm) is proportional to the ammonia concentration in the sample.

Simple, direct and automation-ready. Procedures for measuring NH3 are very desirable.
