When measuring Nitrate in the sample, coexisting Nitrite will affect the result. If you know Nitrite is coexisted, please use the following products for the measrement.

Nitrite range Product name Model Remark
0.05mg/L Reagent Set for Water Analyzer No.18 Nitrite LR-NO2 —
0.05mg/L - 10mg/L Pretreatment Reagent for Nitrate NO3-RA Required heating instrument.

 

In this analyte the procedure should be divided into 3 methods according to the sample state. Be careful that each method uses their specified reagent.

Methods NO3_1 Nitrate (NO2 = 0 mg/L) NO3_2 Nitrate (NO2 ≤ 0.1 mg/L) NO3_3 Nitrate (NO2 0.1 - 10 mg/L)
Range 0.20 - 5.00 mg/L (ppm)
Method Reduction and Naphthylethylenediamine
