Special remarks: Set consists of 2 cartons: 27140-45 and 26721-45.

27140-45 = TN Hydroxyde reagent solution (2714045), Persulfate Powder Pillows (2671846); 26721-45 = TN Acid reagent C solution (2672145), Bisulfitreagent A Powder Pillows (2671946), Indicator reagent B Powder Pillows (2672046)

16 mm TNT products can be evaluated on DR900 only.

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.
