Merck Nitrite Test Paper from Germany 1.10007.0001

Method: Test paper colorimetric method, 2-5-10-20-40-80 mg/L (NO)₂^-), MQuant^®

Nitrite is a pollution indicator. Therefore, it has potential applications in the analysis of drinking water, wastewater, industrial water, and aquarium water. In food analysis, it is particularly important to determine nitrite in meat products, pickling solutions, saltwater, and deep frozen spinach. In MQuant ® On nitrite test strips, nitrite ions react with aromatic amines to form diazonium salts, which then react with N - (1-naphthyl) - ethylenediamine to form purple red azo dyes. By visually comparing the reaction zone of the test strip with the color blocks, nitrite concentration can be semi quantitatively determined. This test strip is highly suitable for pre testing samples in an economical and rapid manner, in order to facilitate the use of quantitative methods such as Reflectoquant^®And SpectroQuant^®Prior to nitrite testing, estimate the concentration of nitrite and possible dilution factors.

Sustainable Development Design:

By exploring ways to improve existing products in our product portfolio, we consistently demonstrate our commitment to the planet and a sustainable future. Recently, we evaluated the current MQuant^®The purpose of the test paper product line is to identify important opportunities to reduce environmental impact while not affecting product performance.

Environmental Contribution:

• Reduced usage of test strips

• Recycled aluminum tube packaging

• Electronic instruction manual
