Add liquid reagent or solid reagent (B tube) 4, covered with caps, mix even 5, wait for a reaction time of 6, the rotation ratio color wheel until two test tubes in the same color Colo ri me tr ic determination of nitrite nitrite test kits In acidic solution sulph an ilic acid or sulph an ilam id e are diazo ti sed with nitrite. The di azoni um salt is then coupled with an aromatic amine, forming an intensely co loured azo dye. Organic colloids, chlorine, hu mic acids and col our ed heavy metal ions interfere. (Reaction principle analogous to AP HA 4500-NO 2-B, EPA 35.1, DIN EN 26777-D 10) Data and ordering information:.
