 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 and 5891, which use zinc and contain a reagent that eliminates nitrite interference. Kit #3519 tests both nitrate and nitrite.
