MACHEREY-NAGEL 985-669 NanoColor Nitrite 4 Tube Toets Instruksie Handleiding

REF 985 669 Robot
Test 6-69 06.16
NANOCOLOR® Nitrite 4

Metode:

Photometric determination with sulfanilamide and N-(1-naphthyl)ethylenediamine

Range: 0.1–4.0 mg/L NO2-N 0.3–13.0 mg/L NO-
Golflengte (HW = 5–12 nm): 540 nm  
Reaksie tyd: 15 min (900 s)  
Reaksie temperatuur: 20-25 ° C  

Inhoud van reagenset:

20 proefbuise Nitriet 4

1 x 100 mL Nitrite A

Gevaarwaarskuwing:

This tube test does not contain any harmful substances which must be specially labelled as hazardous.

Preliminary tests:

As die orde van grootte van die konsentrasie in asample 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.

Inmengings:

Free chlorine, organic colloids and humic acids can cause interferences.

The following ions will not interfere:

< 1000 mg/L Ca2+, Cr(III), Cu2+, Fe3+, Mg2+, Mn2+, Ni2+, Zn2+, Cl - , NO3 - , PO4 3-, SO4 2-

< 10 mg/L Cr(VI)

This method can be applied also for the analysis of sea water.

let wel:

For removal of emulsions, turbidities and colour prior to the test, e.g. for nitrite in cooling lubricants, seepage water from waste deposits etc., use Reagents for sample preparation by clarification precipitation (REF 918 937).

Analytical quality control:

NANOCONTROL Nitrite (REF 925 68)

Dilute 100+ addition solution with distilled water (1+1): 2.1 mg/L NO2-N
Confidence interval: 1.9–2.3 mg/L NO2-N

Verwysing:
