The OndaVia Ammonia Analysis Cartridge is designed to measure ammonia in a variety of samples. Matrices include fresh and drinking water, and refinery process (sour) water. Ammonia is a colorless gas with a strong, distinct odor. In concentrated form, it is caustic and hazardous, yet it is widely found in nature at trace-level concentrations. Ammonia can act as a nitrogen food source and fertilizer, while also being a waste product generated by aquatic organisms. Our method for ammonia analysis builds upon the long-standing salicylate method with the addition of an internal standard and the use of Raman spectroscopy for measurement. The value reported is NH3 (ppm) and may be converted to NH3-N by dividing by 1.216.
Cartridges are supplied ten (10) per box.
