Application: This electrode is used to measure the concentration of nitrite ions in aqueous solutions. Measurement is not affected by differences in sample color and turbidity. There are many types of nitrogen oxides (NOX), including nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2), nitrous oxide (N2O3), nitrous oxide (N2O4) and other compounds, but the main ones are NO and NO2, which are common atmospheric pollutants. Among them, nitrous oxide (N2O), nitrous oxide (N2O3), and nitrous oxide (N2O4) are extremely unstable in general environments and are easily converted into NO2- (nitrite ions).
