NANOCOLOR® total Nitrogen TNb 60 tube test 0-92, Range 3 - 60 mg/L N, 20 determinations
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.
Modifications:
- Addition of the compensation reagent as NANOFIX capsule
Benefits:
- Simplified test procedure
- Fast and time saving working
