Product Information

Nitrite, an intermediate in the nitrogen cycle, is formed during the decomposition of organic matter but readily oxidizes to form nitrate. Nitrites are useful as corrosion inhibitors, preservatives and more.
Using the colorimetric method, nitrite reacts to a pink dye. The intensity of the color is directly proportional to the concentration of nitrite in the sample.

An ampoule is immersed in the sample and the tip is snapped off. The correct volume of sample is drawn in and a small inert gas bubble forms. Sample and reagent are mixed by tilting the ampoule so the bubble travels from end to end. In two minutes or less, the resulting color is compared to the appropriate color standards (comparators or color chart) to quantify the result.

Approx. analysis time 11 minutes. Range 0–20 and 20–100 ppm.
