LaMotte 3119-01, Individual Test Kit (Nitrate Nitrogen)

LaMotte 3119-01,  Individual Test Kit (Nitrate Nitrogen) 

The nitrate is reduced to nitrite by cadmium or zinc and this undergoes diazotization/coupling to form a pink color. All kits below use cadmium except #3354, which uses zinc and which also contains a reagent that eliminates nitrite interference. Kit #3519 tests both nitrate and nitrite. The kit #3119 uses one comparator that contains both nitrate and phosphate standards. The phosphate method in kit #3119 is an ascorbic acid reduction.
