NANOCOLOR Standard test Nitrate range:0.1 - 30.0 mg/L NO3-N 4 - 140 mg/L NO3-. Photometric determination with 2,6-dimethylphenol in sulphuric acid / phosphoric acid mixture. In acidic solution, nitrate ions react with 2,6-dimethylphenol to form 4-nitro-2,6-dimethylphenol, which can be evaluated photometrically.
Approved Reliable and comparable results The reaction basis of NANOCOLORtests is based on international approved standard methods like DIN-, EN-, ISO-, EPA- and APHA.
Precise Easy handling and highest accuracy All NANOCOLORtests 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 NANOCOLORtest box is equipped with a colour coded label and can be identified clearly by its colour.
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.
