MACHEREY-NAGEL 985668 Tube Test Nanocolor Robot Nitritt 2
Method
Photometric determination with sulfanilamide and N-(1-naphthyl)ethylenediamine
- Range: 0.003–0.46 mg/L NO2-N 0.02–1.5 mg/L NO2
- Wavelength (HW = 5–12 nm): 540 nm
Contents of Reagent Set
- 20 test tubes Nitrite 2
- 1 test tube with 6 mL Nitrite 2 R2
Hazard Warning
- Reagent R2 contains citric acid 20–40 %.
- For further information ask for a safety data sheet.
Preliminary Tests
If the order of magnitude of the concentration in a sample is not known, a preliminary test with QUANTOFIX® Nitrite (1–80 mg/L NO2 –, REF 913 11) rapidly gives this information. From the order of magnitude, the required dilution can be calculated and prepared directly.
Interferences
Free chlorine, organic colloids, and humic acids can cause interference. The following ions will not interfere: ≤ 3 mg/L Fe(III), Cr(VI). The method can be applied also for the analysis of seawater.
Analytical Quality Control
NANOCONTROL Nitrite (REF 925 68)
