NANOCOLOR® Total Nitrogen Tube Test




The NANOCOLOR® Total Nitrogen Tube Test is for the photometric determination of total nitrogen.

Oxidative decomposition in the heating block with subsequent interference compensation and photometric determination with 2,6-dimethylphenol in sulphuric acid / phosphoric acid mixture.  All organic and inorganic nitrogen containing substances are oxidised to nitrate in acidic solution. In acidic solution nitrate ions react with 2,6-dimethylphenol to form 4-nitro-2,6-dimethylphenol, which can be evaluated photometrically.

New modifications:
• Predosed decomposition reagent directly in tubes
• Addition of the compensation reagent as NANOFIX capsule
• Simplified test procedure – no addition of reagents with a spoon anymore
• Fast and time saving working – one working step is eliminated because of the predosed decomposition reagent

Compatible with the following photometers:
