The determination of nitrate levels in fruit or vegetables help decide whether a given delivery batch can be released for use in a specific product like baby food.

In the presence of an acidic buffer, the nitrite reacts with an aromatic amine to form a diazonium salt, which in turn reacts with N-(1-naphthyl)-ethylenediamine to form a red-violet azo dye, the concentration of which is determined reflectometrically. Reflectoquant® Nitrate Test Strips are used with the Reflectoquant® RQflex® 10 Meter Reflectometer Analysis System. Measuring Range: 5 to 225ppm. 50 Nitrate Test Strips/Pack.
