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
