The Urea/Ammonia (Rapid) test kit is suitable for the specific and rapid measurement and analysis of urea and ammonia in water, beverages, milk and food products.

Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.

UV-method for the determination of Urea and Ammonia in
foodstuffs, beverages and other materials

Principle:
(urease)
(1) Urea + H2O → 2NH3 + CO2

(microbial glutamate dehydrogenase)
(2) 2-Oxoglutarate + NADPH + NH4+ → L-glutamic acid + NADP+
+ H2O

	Kit size:  50 assays of each Method: Spectrophotometric at 340 nm Reaction time:  ~ 8 min Detection limit:  0.13 mg/L (urea)
                                          0.07 mg/L (ammonia) Application examples: Wine, grape juice, must, fruit juices, soft drinks, milk, cheese, meat,
processed meat, bakery products, seafood, fertilizers, feed,
pharmaceuticals, cosmetics, water (e.g. swimming-pool water), Kjeldahl
analysis, paper (and cardboard) and other materials (e.g. biological 
cultures, samples, etc.) Method recognition: Methods based on this principle have been accepted by NEN and MEBAK
