General description

Method: photometric 0.2 - 17.0 mg/l NO₃-N 0.9 - 75.3 mg/l NO₃⁻ Spectroquant®
This Spectroquant® Nitrate Cell Test allows the accurate quantification of nitrate in seawater samples. Nitrate is an essential nutrient required for the growth of animals and plants. However, elevated levels of nitrate can be a health risk, in particular for pregnant women and infants. Therefore, nitrate levels in water sources are regulated in many countries.
Method applied: In strongly sulfuric solution, in the presence of chloride nitrate ions react with resorcinol to form a red-violet indophenol dye that is determined photometrically.
The Spectroquant® Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet.
All our Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.
