Nitrite HR Test Kits
About this item
The NED method is widely used in the quantitative analysis of nitrite and nitrate in water samples. NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, lower detection limits and measurement ranges are possible vs. chromotropic acid kits. In addition, the nitrate measurement uses only zinc which is less toxic than cadmium, making handling and disposal safer.
Measurement via zinc reduction only, safer handling and disposal
Improved sensitivity and faster analysis time
Simplified reordering, visual refills include NED, Zn, Acidifier and buffer under single catalog code
CHEMetrics Nitrate Test Kits use the N-(1-Naphthyl) ethylenediamine (NED) method to measure nitrate in potable, surface, storm, ground, sea, and wastewater. These kits offer improved sensitivity and faster analysis time (10 vs. 13 min) compared to our current chromotropic acid-based kits.
Like the legacy chromotropic acid reagent, NED readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored pink azo compound. The intensity of the color is directly proportional to the concentration of nitrite in the sample. Due to the significant intensity of the developed color even at very low nitrite/nitrate concentrations, we are now able to offer lower detection limits and measurement ranges than our chromotropic acid kits provide.
