• Distilled-Ammonia :  0 – 1  to  0 – 5 mg/L 0.02 mg/L
• Analysis Principle
• Phenol - Distillation of Phenol under 145 ℃ and the subsequent reaction of the distillated with alkaline ferricyanide and 4-aminoantipyrine to form a red complex which is measured colorimetrically at 505 nm
• Cyanide - Converted to cyanogen chloride by reaction with chloramine-T which subsequently reacts with pyridine carboxylic acid to give a blue colored complex. In the case that metallic cyanides have to be assayed, 145℃ distillation stage and 60℃ heating procedure are incorporated measuring at 630 nm
• Fluorine - Distillated at 145℃ with sulfuric acid and the distillate react with lanthanum-alizarin to from blue complex measured at 630 nm
• Distilled Ammonia - Distillation Step with 120℃ is required, after distillation, alkaline phenol and hypochlorite react with ammonia to from indophenol blue complex measured at 630 nm
