Nitrate Octa Slide Test Kit
The Nitrate Octa Slide Test Kit by LaMotte is used in water quality testing for aquaponics. 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.
