Description
Description
Packaged reagents NitraVer 3 Powder Pillows (2107169) for the determination of Nitrite from Hach.
Аpplication: For water, wastewater, seawater.
The reagents are hermetically sealed in foil sachets, which provides them with a long shelf life. The reagent is simply poured into the measuring cuvette along with the sample. The analysis is carried out visually, for example using a color disc or with a HACH LANGE photometer.
Summary of method: Nitrite in the sample reacts with sulfanilic acid to form an intermediate diazonium salt. This couples with chromotropic acid to produce a pink colored complex directly proportional to the amount of nitrite present. The measurement wavelength is 507 nm for spectrophotometers or 520 nm for colorimeters.
