TR-103S nitrite mɛtɛrGB7493-87 "Nitrite Nitrate Determination Spectrophotic Method" në phosphoric acid medium, pH value is 1.8±0.3, nitrite reacts with para-amino benzene sulfamide, producing heavy nitrogen salts, then coupled with N-(1-naphthyl)-ethylamine to generate red dye, to spectrophotometer determine its absorption, after calculation by microcomputer chip processing to show direct nitrite content (mg/L).
