QUANTOFIX® Nitrate / Nitrite test strips: Quick and easy determination of nitrate and nitrite. Features: • These test strips are for the rapid and reliable determination of Nitrate and Nitrite in solutions. • The easy dip-and-read-procedure of the test strips provides a reliable result within 1 minute. • Nitrite is an undesired byproduct in cooling lubricants. It allows the formation of carcinogenic compounds. Cooling lubricants are therefore regularly tested for Nitrite. • In natural and drinking water Nitrite can lead to infant mortality and dead aquatic life. • The EPA primary drinking water standard is 1 mg/l. • Nitrate is also a byproduct of biological decay from plant and animal matter. High concentrations can be found in rural, farming areas where fertilizers are regularly used. Also, industrial effluents may contain Nitrate in higher levels. The EU threshold value is 50 mg/l and can be safely controlled with QUANTOFIX® Nitrate / Nitrite test strips. • Often different foods need to be testes for their nitrate content. Nitrate is often prevalent in preservatives or present in food due to over-fertilization. Excessive nitrate concentrations in food can have adverse effects on food quality and consumer health. • Regular nitrate tests in the food industry are therefore very important. • Additionally, Farmers use this test to control the nitrogen content in soil to estimate the amount of fertilizer needed. • In ponds and aquariums Nitrate is often tested instead of Ammonium to control the water quality. • QUANTOFIX® Nitrate / Nitrite test strips are the ideal choice to check nitrate and nitrite levels quickly and safely. Specifications: • Presentation: Tube of 100 test strips. • Color reaction: white → red-violet. • Gradation: 0 · 10 · 25 · 50 · 100 · 250 · 500 mg/l NO3– (Nitrate); 0 · 1 · 5 · 10 · 20 · 40 · 80 mg/l NO2– (Nitrite).
