About this item

Nitrate is reduced to nitrite using cadmium as the reducing agent. The resulting nitrite concentration is then determined colorimetrically. This method is applicable to drinking and surface waters, as well as domestic and industrial wastes.

Ideal for low- to medium-range colorimetric analysis of water quality

CHEMets® test kits utilize self-filling ampules and vacuum pulls the sample up from a snap cup into the ampule when the tip is broken off. After tilting the ampule several times to mix the sample and reagent and waiting for the color to develop (usually 2 minutes or less), the analyst quantifies the result using the provided cylindrical comparator (for concentrations ≤1ppm) or flat comparator (for concentrations ≥1ppm).

Nitrite will interfere with this test. Results are expressed as ppm (mg/L) NO₃-N or NO₃.

Nitrate is the most completely oxidized form of nitrogen. It is formed during the final stages of biological decomposition, either in wastewater treatment facilities or in natural water supplies. Low-level nitrate concentrations may be present in natural waters. However, a Maximum Contaminant Level of 10 ppm nitrate-nitrogen has been established for drinking water by the USEPA.

Delivery: Kits come in a plastic case and contain everything needed to perform 30 tests (except distilled water): Refill, Comparator, 25 mL sample cup, syringe, reaction tube with lid, and instructions.
