Print PageThe determination of TKN is performed in 3 steps: 1. Photometric determination of TNb via oxidative decomposition and subsequent reaction with 2,6-dimethylphenol in a sulphuric acid / phosphoric acid mixture (reaction basis in dependence on ISO 11905-1). 2. Analogues determination of the nitrate content without oxidative decomposition (reaction basis in dependence on DIN 38405-D9-2). 3. Evaluation of TKN as deviation of TNb and NO3-N.

- Type: 1.00 €“ 16.00 mg/L TKN, TNb, NO3-N
- Sufficient for: 20 determinations
- Shelf life: at least 1.5 years after production
- Sea water suitability: no

Compact Multiparameter Photometer PF-12 Plus
For easy and fast measurements
Using NANOCOLOR® bar coded test tubes, the measurement is automatically performed after inserting the cuvette into the cuvette slot. The contact with any dangerous chemicals is avoided because the measurement is performed directly in the test tube. This guarantees maximum safety for the user.
Approved
Reliable and comparable results
The reaction basis of NANOCOLOR® tests is based on international approved standard methods like DIN-, EN-, ISO-, EPA- and APHA.
Precise
Easy handling and highest accuracy
All NANOCOLOR® tests contain accurate predosed reagents, that are directly ready to use and calibrated accessories.
Versatile
The perfect test for every request
For all important parameters in water and wastewater analysis, a large number of tests with different ranges is available.
Unique
No mix up of tests Every
NANOCOLOR® test box is equipped with a colour coded label and can be identified clearly by its colour.
A full overview of all reagents and equipment can be found in the NANOCOLOR Analysis System Brochure.
