Th-zx400 total nitrogen water quality automatic analyzer
Th-zx400 total nitrogen water quality automatic analyzer
Product Description:

At 120-124 ℃, the nitrogen of nitrogen-containing compounds in the sample is converted into nitrate by alkaline potassium persulfate solution. The absorbance a220 and A275 are determined by ultraviolet spectrophotometry at the wavelength of 220nm and 275nm respectively. The corrected absorbance A is calculated according to the following formula. The content of total nitrogen (in n) is directly proportional to the corrected absorbance a. A=A220-2A275
