Seed viability Test Kit (Bromothymol Blue BTB method)

As one of the main nitrogen sources for plant absorption and utilization, ammonium nitrogen synthesizes various important biological molecules including amino acids, participates in the nitrogen metabolism process of plants, and has a very important impact on plant growth and crop yield.
According to the reaction principle of ammonium nitrogen and indophenol blue, this method uses phenol-hypochlorite direct chromogenic method to determine ammonium nitrogen. The generated blue indophenol is proportional to the concentration of ammonium nitrogen, and has a special absorption peak at 630 nm. According to this, the content of ammonium nitrogen in the sample can be calculated from the absorption value.
