Method: Photometric, 0.010 - 3.00 mg/L (NH4-N), Spectroquant^®
The method is analogous to EPA 350.1, APHA 4500-NH3 F, ISO 7150-1, and DIN 38406-5.
This Spectroquant^® Ammonium Reagent Test allows the cyanide-free quantification of ammonium in wastewater, groundwater, surface water, and seawater. Typically, ammonium enters water sources as run-off from fertilized agricultural areas and enhanced levels are important indicators of fecal pollution.
Further fields of applications are the analysis of foods & beverages and of environmental and agricultural samples (e.g. soil).
