Nitrate analysis of water is one of the most commonly used analytical methods in environmental chemistry.

Nitrate Analysis
Nitrate analytical methods are frequently employed in water characterization. T his is because nitrate pollution of water presents a significant health risk for humans and animals. Most US EPA certified nitrate analysis methods use the heavy metal cadmium to reduce nitrate in the process of nitrate analysis. Cadmium is a toxic chemical that is regulated by the US EPA under the Clean Water Act. Thus, nitrate analysis with automated equipment using cadmium puts the person running the analysis at risk of being exposed to a toxic chemical. The waste generated during automated nitrate analysis puts the environment at risk of pollution with a toxic chemical. While proper waste disposal can reduce risk of environmental pollution, only an alternative method will eliminate the risk for the person doing nitrate analysis.

NECi has developed an alternative, the Nitrate Reductase Nitrate Analysis Method (Reference 1 - see list below) based on Superior Stock Nitrate Reductase (NaR) . The NECi Method is a "Green Chemistry" approach, which is "sustainable", and involves no toxic chemicals. The NECi Method also generates no toxic waste which requires special disposal procedures in most circumstances.

Recent studies have shown that he Nitrate Reductase Nitrate Analysis Method (Reference 1 - see list below) is equivalent to cadmium based nitrate testing when using an automated analyzer or manual nitrate analysis (1-6). NECI Autoanalyzer Reagent Kits (ARK) for continuous flow analyzers (CFA) and Flow Injection Analyzers (FIA) are now available.

Why not try the NECi Method in your autoanalyzer equipment and make all your nitrate testing safe for the analysts and the environment?
