What are the advantages of NECi NTK products over other commercial methods for nitrate analysis?
2.5 A: Most other commercial nitrate analysis methods use a heavy metal such as cadmium or zinc for reducing nitrate to nitrite. Heavy metals, especially cadmium, are toxic. So using nitrate analysis systems dependent on cadmium present a health risk for both the person doing the analysis and for the environment since cadmium is difficult to dispose of. NECi NTK systems which use natural NaR and NADH for nitrate analysis are both safe for the user and the environment. Since NECi NTK systems are as accurate, if not more accurate, than other commercial systems, NaR/NADH based systems are a better choice.
