The SM 4500-NO3 B method, which includes a test method for the determination of nitrite / nitrite nitrogen, has been developed within the scope of the National Environmental Methods Index (NEMI), which creates a database containing environmental methods, protocols, statistical and analytical methods and procedures and develops standard methods.

Determining nitrate is not easy because a wide variety of components are likely to be present. This standard includes numerous methods used to detect nitrate. For a specific application, it is necessary to implement a test strategy by reviewing the sample content, concentration range, and data requirements, and considering the advantages and limitations of each method.
The SM 4500-NO3 B method includes an ultraviolet (UV) light technique measuring nitrate absorbance at 220 nm and is considered suitable for screening uncontaminated (low organic matter) water.
If necessary, a sample should be screened and then an appropriate method should be selected for the concentration range and possible interactions. Nitrate ion chromatography, capillary ion electrophoresis, or the methods shown herein may be employed. In this standard, the valid ranges for the methods that can be applied are given separately.
In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests performed in this context, there are nitrite / nitrite nitrogen determination (SM 4500-NO3 B method) services.
