3. Operation

1. Dilute the standard solution with distilled water to 15mL in tube1.

2. Wash tube2 with testing liquid before testing.

3. Fill tube2 with testing liquid to 15mL, add on pack of 10030 reagent, sway and wait for 5 minutes, then add one pack of 10040 reagent, wait for 10 minutes.

4. Compare the shown color of tube2 with tube 1, if the color is lighter than tube1, concentration of nitrite is blow 0.002mg/L, which means the water is suitable for drinking.

4. Background

Nitrite is a contamination indicator and therefore an important parameter that is tested regularly in a wide variety of settings. To determine the nitrite concentration, very often nitrite test kit are used. Nitrite is an undesired byproduct in cooling lubricants. It allows the formation of carcinogenic compounds. Cooling lubricants are therefore regularly tested with nitrite test strips. Additionally, nitrite is an important parameter for aquacultures and fish farming. Nitrite is formed in the decomposition of organic material. High levels can lead to the disruption of filtration units. Moreover, long-term exposure can be harmful to fish. In natural and drinking water Nitrite can lead to infant mortality and dead aquatic life.
