Description
Cuvette tests TNT 2672245 for the determination of Nitrogen, total from Hach.
Аpplication: For water and wastewater.
Cuvette test (Ø 16 mm) completely equipped with all reagents, optimised for reliable measuring results and easy handling. Sealed ampoules of 16 mm contain everything you need for mixing and measuring. The package contains all the necessary reagents and ampoules.
Parameter: Nitrogen, total.
Special remarks: 16 mm TNT products can be evaluated on DR900 only.
Set consists of 2 cartons: 26717-45 and 26721-45
26717-45 = TN Hydroxide reagent (2714045), Persulfate Powder Pillows (2671846); 26721-45 = TN Acid reagent C (2672145), Bisulfitreagent A Powder Pillows (2671946), Indicator reagent B Powder Pillows (2672046)
Summary of method: An alkaline persulfate digestion converts all forms of nitrogen to nitrate. Sodium metabisulfite is added after the digestion to eliminate halogen oxide interferences. Nitrate then reacts with chromotropic acid under strongly acidic conditions to form a yellow complex. The measurement wavelength is 410 nm for spectrophotometers or 420 nm for colorimeters.
